A preterm birth (sometimes called “preterm labor”) is a birth that takes place more than three weeks before the baby’s estimated due date or before the start of the 37th week of pregnancy. At Weill Cornell Medicine, we understand that preterm birth can be frightening and overwhelming. We are here to support you and your baby’s health at all times.

Preeclampsia is a pregnancy complication that causes high blood pressure, generally beginning at the 20th week of pregnancy.

This condition can be dangerous for you and your baby. It can prevent your baby from receiving oxygen and nutrients. It can also harm your liver or kidneys. With expert care, however, this condition can be managed so that you and your baby will be as healthy as possible.

The placenta is the organ that develops in the uterus during pregnancy. It provides nutrients and oxygen to your baby, as well as removes waste from your baby’s blood. The placenta is attached to your uterus and connects to your baby’s umbilical cord.

If you deliver your baby vaginally, the placenta will be delivered afterward. If you have a Cesarean section, the placenta will be removed by your surgeon after your baby is delivered.

Congratulations on your twin or multiple pregnancy!

At Weill Cornell Medicine, we understand that expecting twins, triplets or multiples is very exciting. It can also feel overwhelming or isolating. Many aspects of your pregnancy are different from a one-child (singleton) pregnancy.
