Many first time mothers experience the schedule of OB visits as informative: there are few visits in the beginning of the pregnancy and many near the end and one might take that to mean that there is more going on at the end than the beginning of gestation. 

In fact, there is a tremendous amount of activity going on in the opening weeks of pregnancy, but until now, we understood very little of it, and had very limited ability to change our trajectory with any move other than delivery.

Today's guest, Dr. Carl Weiner, has mined some of the early data of the first trimester to allow him and his team to predict whether a premature birth is likely on the horizon when the pregnant person is 12 weeks pregnant. Today we'll talk about his exciting work.
