Twin Pregnancy Week 12
At this stage of your twin pregnancy all organs and structures are fully formed but the organs are still developing rapidly.
From this point onward, your doctor may be able to detect your babies’ heartbeats by a doppler. Your babies’ stomachs, livers and bladders can be seen with an ultrasound.
At this time your babies’ genitals are beginning to show their differences. However, the earliest that an ultrasound technician can differentiate between male and female babies will be around week 20. So if you had an ultrasound, you still would not know the gender of your babies.
At week 12, the chances of having miscarriage has dropped a great deal.
