So my best friend got pregnant for the first time. They just started trying. Her family has a history of miscarriage so her doctor told her to go ahead and come in to check her levels. Long story short her levels hadn't risen a lot. It was 40 when she went in. She doesn't remember the second draw number cause she was really disappointed. They said her progesterone was low. It was 17 and it needs to be 21. They are putting her on supplements.

Will progesterone help the pregnancy stick and grow? I've never dealt with that side of pregnancy. We are just curious and wondering. She thinks it won't stick and is assuming she will miscarry.
