progesterone shot, good or bad?

Progesterone is fine. Its a hormone your body makes naturally. I'm supposed to be on it also because I have a history of preterm labor and delivery but due to some issues with my insurance I've only taken it once. I don't know where you read that it can cause stillbirth but that is wrong. If progesterone could cause stillbirth women would have problems with it since it is a naturally occurring hormone. The reason drs give it to patients with a history of preterm labor and delivery whether its family or personal is because it is thought the cause of those is your body not making/producing enough progesterone. Hope this helps.
