How do you know you are having twins

With the advance in technology and health system, it is very rare these days to have a surprise twin pregnancy. Most people will know they are having twins from the beginning or at least form week 16 when a routine ultrasound is scheduled in most parts of the western world.

You may end up having an ultrasound test earlier if your doctor suspects twins, as it was in my case. I believe when you do the blood test to confirm your pregnancy and the HCG levels (pregnancy hormones) are too high, it can either indicate a twin pregnancy, or you have been pregnant longer than you anticipated.

Even if you do not have any ultrasound test, at some point with regular check ups your doctor will hear two very distinct heart beats.

Also your tummy size is a good indicator of what you are carrying in there ladies!

Another possible indication of twin pregnancy is that your morning sickness and other early pregnancy symptoms may be exaggerated like severe nausea and vomiting.

If you suspect a multiple pregnancy just ask your doctor to confirm your suspicious.

My pregnancy is on highspeed also ! I cramped n stretched out a belly extremely! I’m always have such bad nausea! My back hurts I have a migraine ! Hormones so high I could feel I was pregnant the week after I conceived! And from the first pregnancy test it was so early and still show a light line , I have 2 other children and didn’t know anything till 8 weeks or more ! Help!!! Could I have be having twins

  3. Hi ladies:
    I am currently 19 weeks pregnant with b/g twins. I just found out last week at my 18 weeks u/s. My doctors had no clue before then. I did have a very strong maternal instinct that it was twins. I had just had a daughter in a singleton pregnancy the year before and I noticed the differences. I had alot of fatigue and sickness with both of my pregnancies. The difference was everything happened so fast. I began to grow really quickly. I had heartburn extremely early. I was in a highspeed pregnancy. I went for my routine prenatal appointment and the doctor found the heartbeat way down in my pelvis. Two days later my blood pressure shot up and they told me to come into to the office. They found the heartbeat on the opposite side above my belly button. I asked the doctor is she sure its one baby. She said she only heard one heart beat. I went home and told my husband I think it’s two. He just laughed it off like I was crazy. Several weeks later I went in to get the first u/s and after about 30 seconds she looked at me and my husband and said you have twins. My husband said you knew omg I cant believe it. I truly believe that you will definitely have your signs and your body and your instincts will tell you if you are having twins. It definitely helped that this was not my first pregnancy. I was able to compare the differences.

  4. I use I was having twins from the start there was too many signals, server back ache nausea came on way earlier then normal, and wth all my other pregnancy I could feel the fetus even at 5 weeks, it weird I know but I could, it was like a pressure pushing on the womb…anyway I could feel two, first I thought I was mad, my partner thought the same, but I had to go to EPU due to some little bleeding and be hold I’m having twins…my first response was to my partner “told you so”… I will trust my gut feeling next time….

  5. before i even get pregnant i knew that me and my husband will be expecting twins due to our genes. anyways the 1st was i’m always hungry every 2-3hrs even i ate a lot. my baby bumps is bigger than singleton. my coworker always jokes around that he thought i have multiple babies lol i guess he was right.
    my sense of smells is stronger. i’m almost 31wks now and can’t wait to see my twin boys =)

  6. I just found out I am pregnant with twins. I am having a horrible experience. At 10 wks I have went through a lot. with the constant fatigue painful back and it feels like they r coming out of my vagina all the time. the docs are really worried about them but I know my babies r troopers. Who would have thought I would be having twins! im excited but worried at the same time

  7. I am 19 weeks and just found out I am having twin girls.  I am….overwhelmed to say the least.  haha  My tummy was a little bigger than I thought it should be, but I never once got sick.  I did, however, have mild afternoon nausea.  I’m excited to have found this website!  I’ll need as much advice as I can get!

      Hi Meredith,

      Welcome to the site. Ask all the questions you like and we will be more than happy to help out.

      All the best,

  8. I am 5 weeks pregnant, and I am so short of breath. I dont’ have ashma or any respiratory disease. Could that be a sign that I am carrying twins? My 1st US is scheduled for next week. But I would love to know before. I feel I can’t wait to know. Please help!

  9. I have been having different symptoms as well. This is my second pregnancy and my first is 5 years old.
    I am only 7 weeks right now.
    My boobs have been EXTREMELY sore (and were sore 2 weeks before finding out I was pregnant). I have been EXTREMELY tired (and have been since about a week to 2 weeks before finding out I was pregnant). I feel heavy like I have a big belly already but I don’t. My pants line is tight and find I have to undo the button and zipper while in a vehicle otherwise it hurts. I look at myself and I think that I have a bump already but I’m unsure if it’s just bloating? I am also VERY moody (hormonal)!!!
    The thing that throws me off is that I haven’t had bad morning sickness. Not like my first, which was horrible. I have a constant feeling of nausea all day and that’s it.
    I don’t have my first prenatal till September. 26, so I’m still a ways away from an ultra sound or anything.
    Has anyone else had these symptoms while pregnant with twins??? Any advice or thoughts that I may be pregnant with twins, would be appreciated! 

    • Mother of Twins says:

      Hi Christy,

      By the symptoms it could very well be twins. But as you already know it needs to be confirmed by ultrasound. I personally did not have any special symptoms at week 7 to suspect twins. Every pregnancy is different.

      All the best.

      • Yikes! lol **feeling excited and nervous** lol
        I’m definitley wondering  more now! And I’m hoping to get into and ultrasound sooner than later!

        Anyone else who has something to add with your greatly appreciated! 🙂

    • Yes i just kept bugging out like why my pants lineing hurts soo bad when i sit on the bus or why my belly was ova my buttin i was so lost then at 10 weeks i was told i was haven twins im 16 weeks now n it still feel unreal im soo happy n so are my other 3kids

    • just wondering, did you end up having twins?? ????

  10. Hi Ladies, I am in my 11  week with my first pregnancy and feeling no sickness, nausea nor vomiting but i am experiencing abdomen cramps and tightness its really extreme tightness which sometimes i confuse on how to sleep any advise please.  

    • hey suzu, try sleeping on your right side with a pillow between your legs, it helps with being uncomfortable and it will allow the baby (s) and you to get better blood flow.

My OH thinks I’m mad but he now can see that I’m very large for only 6 weeks…! Twins??? Or maybe one very determined boy as my first pregnancy was a girl…. Fingers crossed for a healthy, happy baby/babies xxx

  12. Hi i am prgnant in 11 weeks now, on my 6 weeks i went to the doc to make ultrasould to confirm my prgnancy. Thw doc was found twins.  I am very happy that time. However, on 10th weeks of prgnant i went to other doc but she only found single. However she can’t confirm it yet. Hmmmm.. hmmmm

    • Mother of Twins says:

      In such cases you most likely need to do an ultrasound. According to my doc twin pregnancies are normally confirmed at week 12. Hope all goes well for you.

  14. I’m six weeks pregnant with my 3rd child, both my previous pregnancy’s had no symptoms apart from heart burn later on and I was rather energetic early on. This time I’ve been feeling extremely tired all the time even waking up on the morning is really difficult and I find myself falling asleep after tea. My breasts are so sore the slightest knock feels like a punch upon a bruise and I seem to be angry all the time over nothing. Last night I felt like butterfly’s in my stomach a lot like a tickle on the inside. I know not every pregnancy is the same but could any mother of twins relate to this as I have the feeling there’s more than one.

    • I am 12 weeks pregnant and I am expecting twins. I have had a singleton pregnancy and noticed some differences with my current pregnancy. I felt nausea and hot flashes before I had even missed my period, I didn’t feel these symptoms as early with my singleton pregnancy. I have been much more nauseated this time than I did with my singleton pregnancy. I am already showing to the point where it’s hard to hard to hide my baby bump. I am much bigger this time than I was with my singleton pregnancy. I have been much more tired and emotional this time. Also everyone says it’s not possible but I’ve felt movement since about 9 weeks and I didn’t feel movement until way later with my singleton pregnancy. 

    • I forgot to mention. I had several dreams that I was having twins. I had a feeling that I was having twins. 

    • I am 6 weeks , and highly feel like i am having multiples!!! My hcg level went from 363 to 2,041 in four days , ultrasound scheduled for Feb 23rd~…. I am already tired but with this one here , i hv to sit or lay down all day long .. I have 3 girls … i will keep u posted….

  15. Im 12 weeks and 1 day with twins only found out last week thats it twins coz i had some bleeding and pain ive been on bed rest for week and due for scan again this sunday hopeing everythink ok this is my 5 th pregance 3 boys 1 miscarriage at 12 weeks 

  16. I am about 7 weeks pregnant. I am having extreme nausea, an extremely strong sense of smell to the point that if there is any kind of strong scent that I start gagging , and extreme fatigue to the point I am almost unable to get anything done without taking at least a two hour nap. I think it’s twins but my fiancé doesn’t I want to know what you think. Could it be twins?

    • Mother of Twins says:

      Hi Lisa
      Any pregnancy is different. It sounds like it can be. But if it is your first pregnancy, it could be your body adjusting to all the hormones too.
      At your checkup your doctor may suspect a twin pregnancy if your hormone levels are too high.
      Best of luck.

  17. rebecca mcneill says:

    I am about 4 weeks pregnant. this is my second pregnancy and feel like I might be having twins. I had to stay in hospital for 2 days and they did blood tests and said my hormones were at the 4000 range and I have a really high blood pressure. does this mean I could be having twins? I am constantly tired as well. could it be twins?

  18. Hi, I am 10 weeks pregnant. This is my 4th pregnancy. With my other three I had no such feelings than I have 4-5 weeks I went to er because I was having terrible back pain. The ultrasound saw only one yolk sac. I know my chances of having twins r very slim. My question is, is it to early at about 5 weeks to tell if u r having twins? By the way I haven’t start my prenatal visit yet due to my constant travelling…

    • I had to have an ultrasound early because I was bleeding around my 7th week and when they did mine they only found one yoke sack, but I have heard that even if its just one its possible to still have twins because its so early on they cant see the actual baby don’t know how accurate that is, now at week 16 i’m going in for my ultrasound in a couple weeks, and with this pregnancy I’ve gained about 10 pounds and I look like i’m about due I have had a lot of things different with this pregnancy than with any other I have had. I have 2 living and 1 miscarriage this would be my 4th pregnancy and like one of the lady’s commented earlier in oct. 2013 i’m having all the back pain, the pain down below, the heaviness of the uterus, the migraines, the constipation(thank goodness for dulsolax laxatives), the sharp pains in the uterus and cramps and i’m so tired all the time that if I get up out of bed for more than an hour i’m ready for a nap, can anyone help me figure out if im having twins or just a normal pregnancy?

  19. I m 8 week pregnant but my stomach is showing already and I m always tried can’t sleep at night and my Moody’s keep on changing every hour symptom are getting more and more it could be that I m carrying twins please help

  20. I am 39 years old. I am 16 weeks, 3 days pregnant. I have had from early on and still have the normal nauseous feeling as I have with all of my children. It seems like I feel sick on my stomach all day and through the evening, the feeling comes and goes. I feel like my stomach is so big. I have had 2 ultrasounds, one when I was 6 weeks and the second when I was 9 weeks. The dr. only saw one baby. But at my last dr. appointment the dr. heard 2 heartbeats through the doppler, I heard 2 heartbeats also. She said that it probably was my heartbeat and also the baby’s. I have headaches alot and backaches. I feel like it could be twins. I see twins everywhere more so now than ever. My next ultrasound is at 19 weeks. I hope I will get some answers.

    • I should also say my hcg level early on was 197 and then the next day it was 724

      • Could anyone please give me their advice. Thank you!

        • Hey I had a miscarriage at 10 weeks with identical twins that shared a gestational sac….. I knew from the beginning even though it was my first pregnancy it was twins, my symptoms were all just so exaggerated, I decided to go for a scan privately as it was doing my head in not knowing and the lady first did an abdominal scan and saw two then as there was no heartbeat and they looked small said she would do a vaginal one and told me she got it wrong there was only one but till no heartbeat….. however it was confirmed when I went to the hospital in floods of tears to confirm the miscarriage that there was infact twins but one must have been hiding behind the other when she scanned me vaginally. So I guess it can happen
          How did your next scan go ? Hope all is well

  21. Gloria. Ross says:

  23. Michelle says:

    I am 8/9 weeks now my first month was hell i had morning sickness thru out the day….. my tumy is already showing and my blader feels so heavy and fill all the time i have headache in the morning when i wake up. Is it possible to have twins?

  24. Shocked&awed says:

    Just found out yesterday that we are having twins!!! I was horrified at the news because this is my first pregnancy and I was scared to have one baby, and to find out its 2!!!!!????!!!!! Wow! After the shock and horror wore off I began to see this as such a blessing and I can’t wait to meet my babies. I’m only 8 weeks but there were two very strong heartbeats!!!! Other than normal pregnancy symptoms, Some of my symptoms have been “running out of breath easily” and extreme food aversions, horrible nausea, very high sense of smell and the line on my vajj rising up to my stomach started very early. Best wishes to all of us mom of twins! What a special blessing!!!

  25. I feel a tightness in my uterus for weeks now. If i am preggo i should be 6 weeks…still the tightness is there. Then i felt an aching pain on the left and the right of my womb, my guess is this is a corpus luteum cyst on either side. I shoukd be pregnant with fraternal twins if such is the case. But i have an u/s tmr so i would know then. Also i had almost black out sorta faintish feelings and awful dizzy spells! Nothing like my first pregnancy. Then too i keep dreaming of twins.

  26. Last week I visited clinic , they check my stomach n measure it den dey told me dat I have “QUERY BIG BABY / MULTIPLE PREGNANCY” so I’m socked plz help. .my headache always

  27. I’m 39 weeks pregnant and 3days but today my doctor told me that I have twins the ultrasound beat at both side is it possible to have twins or the ultrasound made mistake pls help me I’m stressed

    • Mother of Twins says:

      at 39 weeks you are almost done, are not you?
      Ultrasound does not lie. If they see 2, there is 2.
