Twin Pregnancy Week 13

Welcome to the second trimester. By week 13 of your twin pregnancy you most likely look very pregnant – there will be some moms who do not show as much as you can appreciate from their posts.  Nausea is probably a thing of the past.  You must eat properly and take more calories for nourishing your growing babies. At this time your babies faces look more like humans. Their eyes are moving closer and closer together.  Babies toes and fingers are separated by now and ankles and wrists have formed. At this stage the baby twins are about a size of a peach and weigh about half and ounce each.

help you to be more comfortable as your pregnancy progresses. Watch this video amazin video:

  1. I am 13 weeks, pregnant with twins, and am not showing at all.  Hardly looking “very pregnant” as you say, although both babies are right on track for growth and development.  Don’t post things that aren’t true, you only make expectant mothers that much more nervous.

    • Mother of Twins says:

      HI NJS!!

      Just because you don`t show does not mean most other moms are not showing!!! And there is no need to panic over it either. Most moms carrying twins will be showing and looking more pregnant at week 13 compared to those carrying one.
      Sorry if this makes you upset. But this site has helped a lot of pregnant moms in the past.

      • I am 13 weeks and def showing! 

      • I am 13 weeks and I am definitely showing. I’m already in maternity clothes!

      • Hi! I am 13 weeks pregnant and look way more pregnant than I did with my first 2 single baby pregnancies at 13 weeks.

      • I am 13 weeks with twins and looks like i am at least 5 months already. I’ve also gained about 20 pounds already. Having lots of aches and pains and can’t get a comfortable sleep position. Lets not mention waking up at 2 am then 4 am like clockwork every night to pee. I am very happy to say i did not have any morning sickness at all. Can count less than one hand how many times I was nauseous. I can only imagine what the end of the second and beggining of third trimesters hold for me lol.

        • MotherOfSix...AnCounting says:

          I’m pregnant with twin an just found out mines are fraternal an I’m only showing a little an I only weight 120 an had a lot of morning sickness but I see most of you ladies are already showing a lot an I’m 12 weeks an 1 day an when I had my ultra sound the tech said she thinks one is a boy but it’s still early what about you ladies 

    • Hi NJS,
      What was told above is true, am 12 weeks pregnant with twins. And I am looking like 5 months pregnant (carrying one)!!. So every time people asking, they didnt believe its just 3 months, then I have to explain that I am carrying twins.

    • Like stated before, just because you aren’t doesn’t mean you aren’t the minority. This is my second pregnancy (first with twins) and I am not even 12 weeks but show as I did when I was 20 with my first. This site is super informative, there isn’t a lot of information customized to twin pregnancies (that I have found anyway).

      • Im pregnant with twins for the 1st time and becuz i put on alot of weight from carrying my other 3 kids so no that its twin im showing but if u see me youll just think im fat i cant wait till my belly look big and look like im carry babies and no just putting on weight lol

    • Why be so ugly about a website opinion? I’m 13 weeks and pregnant with twins. I’m very much showing. The only thing I can disagree with in this article is that my sickness is still here, all day long. No need to bash their research, every pregnant woman is different. There is still a majority that can ring the same tune which is whom most of these websites are based upon. 

      • This is my 8th pregnancy (2 was a miscarriage) I’m 12 weeks, 2 days with twins. I’m showing! Never been pregnant with twins before. Nausea is still here.

        • This is my second pregnancy with twins. I think they were just offering a simy written outline of what should/could be happening. As for the nausea part, by this time (while it’s still there) it usually is lighter and tarted to fade. If not, it’s perfectly fine! My first twin pregnancy I was sick until 16 weeks. This is my second and I stopped getting sick by week 10. EVERY PREGNANCY IS DIFFERENT. As every body is different. 

      • Kelly allen says:

        Dont think she was bashing research, she just sounds worried is all. Trouble with any pregnancy is some like to compete. Im 13 weeks pregnant with twins for second time and id say a look a bit fatter but doesnt look like im carrying twins just looks like ive had one to many take outs lol. Also still feeling very sick but at least stopped actually being sick so thats a bonus although im getting a lot of migraines ???? dont ever worry if you are not showing the more you show the heavier it will feel. Just enjoy it.its so special. Good luck with it all ladies! Xx

      • Stephanie says:

        I am 41 yrs old. I’m 13 weeks pregnant with twins and these are my 1st and I’m barely showing. Everyone and every body type is different. I do have all day nausea though.. yuck!!! Any site I can get information from or read how others might have a similar pregnancy to mine is helpful and helps me to feel like I’m not all alone in this.
        I appreciate all comments.

    • For those who have already had children they are most definitely showing. I am 5 foot 1 inch, 106 pounds. Have had one child already and am 2 days shy of being 13 weeks and I am very much so showing 

    • Did you even read the whole post before commenting?? It CLEARLY says, MOST women will be showing. She didn’t say all, or give false information. This is my second pregnancy with twins and both  times by 13 weeks I was OBVIOUSLY pregnant. Every pregnancy is different, which every woman already knows (or should). There’s no need to be rude to her seeing as she’s just offering general information. If you don’t like it just move on to another site instead of getting nasty. I know hormones are crazy but that’s no way to act to a stranger. It also depends on your starter weight. Bigger women tend to take longer to show ad they already have rounder bellies. 

    • This post is old but I am 13 weeks pregnant with twins, it’s my fourth pregnancy and I’ve delivered two children. I look closer to 16/18 weeks pregnant!

    • im 13 weeks too and i still dont look as big as i expected i sometimes wonder are they growing ok?

    • Brook Newman says:

      I’m 11 weeks and I am already showing, just happened this week. So by 13 weeks I’ll really be showing. I’m having twins this time around and showing way more and way sooner the I did with my first two pregnancies.

    • I am 13 weeks pregnant with twins and started off at a healthy weight. I am still working out and I look very pregnant already! Each women and each pregnancy are different ! Let’s not forget to celebrate our individual journeys !! 

    • I am 13 weeks and I am showing, you sound very angry. It says you’ll most likely look pregnant not that you absolutely will.

    • I’m currently 13.5 weeks pregnant and have been showing since I was 10 weeks

    • Oh man I’m 12.5 weeks and look the same as 20 weeks with my last pregnancy!!!

  2. I’m 13 weeks with twins. This is my 4th pregnancy and I believe I’m showing a lot.. Though 
    I was bigger with my 3rd.. I guess every pregnancy is different. 
    I am still feeling nausea everyday and it lasts most of the day.
    Oh well I’m hoping it will pass soon so I can enjoy eating again.
    Thank you for your information as it is very helpful for mothers with twins.
    Keep it up 🙂
    Cheers Sara

  3. To NJS,
    I am 13 weeks pregnant with twins as well. I was worried after I read this because I am barely showing. So I asked my doctor, he did inform me that most women do not show that much when carrying twins until 16 weeks. So my conclusion is the “Very Pregnant” comment is a bit misleading as every pregnancy is different. As my doctor says “pregnancy is not black and white, there are a lot of grey areas”.

  4. Ok let’s recap…. Week 13 is basically 3 months of pregnancy. Most women who carry one child will start showing around this time. MOST of us who have carried twins showed MORE around 3 months of pregnancy. “very pregnant” here is relative for this week and yes every pregnancy is different. Some bellies grow more forward and some grow more to the sides.  
    Also if you have read on other sites or books or even this site one sign that COULD mean that you are carrying twins is your belly size. 
    I am not planning on changing what I have written as most moms will read all these comments and hope this explains more. I have always emphasized that each pregnancy is different and this is a general guideline.

  5. I was very active before getting preggo with twins and had a flat tummy.  I did IVF and my ovaries were in overdrive plus I have a large uterus.  At 5 weeks I needed to buy some maternity jeans.  Everyone’s experience is going to be different, of course, and that’s why I’m explaining mine.  If you are overweight (please don’t throw stones here…) then it’s likely you are not going to show for quite some time.  I find it comforting to find a website or blog that makes me feel “normal” at 3 months pregnant but appearing to be 5 to 6 months along.  I find myself justifying my size by expecting twins all the time.  

  6. I’m now 13 weeks with twins and am absolutely showing. Perhaps the meaning of ‘very pregnant’ varies amongst women… 

  7. Hello
    im 13 weeks and 5 days pregnant with twins when I went for my scan they said there is no fluid around one of my twin I have to go to for a twin scan to find out whats happening they said it doesn’t look very well so far and that they cant yet tell me what it going till happen until Wednesday when I go for the twin scan they did say don’t expect a heart with the twin with no fluid is this is devastating. We were so shocked/blessed to be having twins and now to know one will most likely not make it is so hard to wrap my head around. also they said if the other twins does die that they couldn’t say my other twin will be ok I am hoping for a miracle when we go Wednesday and that there is fluid and a good chance for our babys. if anyone is going through the same thing or have good or bad I could do with someone to talk to how know how im felling iv had to wait 6 days knowing that there is something up with one of my twins for the twin scan on Wednesday.

  8. I am 13 weeks with twins and I look like im almost 5 months, im already in maternity wear! at this stage with my first I was no where near this size

  9. I am the father of twins and we are just hitting 13 weeks. I am not showing at all… I mean my fiancée isn’t showing. :-D.
    We are looking for as much information about twins as we can. There isn’t a lot out there… 🙁 In any case, we are due July 11th, 2015. Any Canadians out there having twins? Ottawa, ON here.

    • Hi…I’m 12 weeks and somewhat showing…though not very prominent. 

    • yup in BC, due July 31, hope to keep them cooking till then! or close to then. Best of luck! I am from Montreal, saddest thing is not being able to travel home, think twins will make that too complicated..

  10. I am 13 weeks pregnant with twins. This is my 1st child. i dont even look pregnant. from doing some research online women with previous children look pregant faster so dont worry what these other mommies say. We all are striving for one thing & that is to deliver some healthy children. * paitiently waiting for my baby bump

  11. Good for all of you that don’t look “very pregnant”… Those of us who have already been pregnant 2 or 3 times will probably be the ones who do look “very pregnant”. I also (like someone already posted) look like I did when I was 5 months with my previous two. Everyone is different. Plus I love the belly because I get to share with people that it’s twins that much longer.

    • I am 12 weeks and 6 days with twins and look like I’m 5 months. I’m glad I’m not the only one. I was shocked that I’m already showing so soon. I’m happy to hear it’s normal.

      • Tiffany says:

        I’m almost 13 weeks and I look 5 months pregnant.  I do have 3 other children so twins were unexpected. It’s very hard to find websites or blogs about twins. So the information is really good. Each pregnancy is different but from my reach I have learned that when you are pregnant with twins you show earlier  ( which makes a lot of sense, since you’re carrying two babies ) ijs

      • Yes, I’m 12weeks and 1 day and I’m definitely showing. 

  12. hi,I’m 12 weeks and one day pregnant with twins and its my 3rd pregnancy. I look like I’m 20 weeks gone n ppl are shocked to hear I’m just 12 wks. it is totally a diff experience so far. so if u haven’t started showing well thank God for u but most women even for singletons begin to show by 12 wk
    s. thanks

  13. I personally felt a sigh of relief knowing women are really showing by week 13. Now I don’t feel so hard on myself. 

  14. Lucy Clarkson says:

    I think i am around 12 weeks pregnant now, carry identical twins. Went for a reassurance scan on the 4-12-15 to make sure my baby had a heart beart, due to the misscarriage i had back in march 2015, and found out that ues there was a perfect little heart beat, and another one too! Was so happy! I thought i was 8 weeks, but the women said the babies are both mesureing  7 weeks and 7 and half weeks, so i think am 12 weeks, i am starting to show a little which is just amazing am so happy! Just waiting to go to my next scan due on the 13-01-16, carnt wait!! I also already have a son, who was both 11-10-14, so he will be 20 months when i have my beautiful babies!!! Love this website so much information about twin pregnancies, un like alot of other website!! Thank you!! 

    • Mother of Twins says:

      Congratulations. Very happy for you. Make sure you take care of yourself. Thank you for the complement. Keep us posted.

  15. Pregnant with twins and I am huge!! Third pregnancy and my stomach looks like I am 5 months along! I started showing at 7 weeks. Still nauseous, heartburn just started this week, and minor hip pain. Twin pregnancy is a lot different than my singletons!

  16. I agree with comments above, I am 13.5 weeks and not showing with twins. Your post def made me nervous as if I haven’t been eating enough or not growing them. I think it seems to vary, its my first pregnancy so maybe that makes a difference. I had an US at 10 weeks and they were at normal growth, but my next one is in two weeks so I have to sweat until then. I feel like my uterus is growing, pains in my round ligaments etc… but its still not really poking out as I have seen in some photos for others. Best to not make blanket statements since it can cause unnecessary worry in a difficult time, 

  17. The Twins Father! says:

    13 weeks just had a ultrasound today 3-14-16. Very exciting we are expecting paternal twins. My wife is very excited. Physical appearance barely noticeable…I call it a pudge instead of a baby bump. They measured normal size and heart beat was normal thank God. This is not our first pregnancy so we are familiar but new to twins. God is good. My wife hasn’t had any nausea yet which is great. She is eating great we have made some changes to our diet more salads fruits and less take out. No soda or coffee. I’m nervous I just want them to be healthy. I hope everyone here is having a healthy and loving pregnancy. To all mothers I sincerely give you all the credit in the world you are special and beautiful from head to toe and know that you are truly appreciated! I pray for a healthy and loving pregnancy. 

    Feeling blessed! Eddie the twins father! 

  18. I am 13 weeks and look like 6 months with my single pregnancies! I’m 34, five feet 6 inches tall and non pregnant weight@135 pounds,  I hit 150 at my appointment last week and I’ve been holding steady lol as it freaked me out to already have gained 15 pounds in 3 months especially considering how sick I have been with nausea and actually throwing up.. Thank God the nausea has let up a lot, but not completely ,the last week or so! The downside is I feel like I’m probably going to really start packing on the weight now, even more, since the foods staying down. Its part of it I guess as long as the babies are healthy is all that matters! Still kind of in disbelief that there’s two babies in there! My older kids are totally excited 🙂 it’s going to be a long hot summer! We feel totally bless ed though, God is good! Best of luck to everyone!

  19. I starting to think that MOST WOMEN can’t read lol, see what I did there. Don’t really get with the fuss is about or why ppl are panicking if the article doesn’t say ALL WOMEN. Anywho, I am pregnant with twins and these are my first kids 🙂 I’m 13 weeks and I look about 5 months, my cousin had twins and at 13 weeks she still had abs. My little aliens are perfectly healthy and my due date is sept 27, I still get really sick some days but I’ve always had a weak stomach. To Lucy sorry to hear that everything isn’t going swell but I’ll keep you in my prayer, or put it in the universe, whichever floats ur boat, that you’ll have a successful and healthy pregnancy. Love all hope everyone takes what they need from this VERY informative article.

  20. This is my first pregnancy.  I look huge, like 5-6 months and I barely am 13 weeks. I’m so hungry all the time. I’m happy but terrified, don’t know how big I will turn to be…

  21. Katy Corbitt says:

    I am 13 weeks pregnant with identical twins this is my second pregnancy (1st pregnancy with twins) my pre pregnancy weight was 105 and I have gained 10 pounds so far 🙂 I’m showing just a little but to any one who doesn’t know me they can’t tell I’m pregnant. I’ve gone from a size 0 Jean to a size 5 so far, really my 0’s were to small by about week 8! I think I’m gonna get really big. With my first pregnancy I didn’t start showing until almost 20 weeks. 

  22. KayCeeHayes says:

    I am 13 weeks pregnant with twins and unlike most moms who have left comments – this is my first pregnancy so I haven’t really had much frame of reference until I found this site. Its really been abundantly helpful.. Thanks so much!:)

  23. Mz. nervous says:

    I am pregnant with twins and barely showing . This is my fifth pregnancy one still born just this past April but now 13 weeks pregnant with twins very nervous cause I’m not really showing. My last check up earlier this month said that they were both perfect measuring well and heartbeats great, just awaiting my next appointment on Monday just very nervous because of what I just been through. But I’m going to leave it in the hands of the Lord and stay prayed up.

  24. I am 13 weeks 3 days and already showing thou not so much.This is my third pregnancy and very unexpected.I feel blessed that everything is going so well except the nausea and vomiting.I can’t wait for it to stop and to start enjoying food again.Thank you all for all your informative post.In Africa twin pregnancies are handled with a lot of curiosity and mixed reactions and there is so little information about them.Am glad I found a site with moms going through the same experience as me.Thank you

  25. I am 13wks and 6 days with twins…not showing at all! However when I was pregnant with my daughter I didn’t start showing until 7 months. I’m not small, so that has alot to do with it bigger people have more room in their bellys…so if you big your not going to show as soon as others so don’t panic

  26. Well, I am 13 weeks and the doc says that my uterus is the size it would be at 17 weeks with one baby. Which is perfectly normal.  Most women are showing by now. 

  27. I am 13 weeks today, and showing! Although, it’s sort of that awkward “is she fat?” or “Is she preggo?” phase! However, nausea is far from being a thing of the past! It is all day, every day :(. These two are giving me a run for my money! I just worry about getting enough nutrients for them, since eating is not the easiest thing for me! I’m praying it fades soon and my appetite comes back so I can start eating healthy again and really getting in my protein!

  28. Jessica Hargrow says:

    I am 13weeks today. Its been a rough 13wks. It is so different being pregnant with twins than just one. I have 2 other kids. Right now I’m just praying that I will start getting better from being so sick. I’ve already been in the hospital once & at my 12wk check up had to get fluids. I’ve lost down to a 140lbs from 158lbs. Just ready to be able to eat & give them what they need. I’m still tryinf to find a vitamin to take that won’t make me sick. I’ve tried everything.

  29. MotherOfSix...AnCounting says:

    I have a question for you Aimee my doctor told me I might have have to get a steroid shot at 24 weeks to make sure my twin lungs develop did you right now I’m 13 weeks today
