Progesterone Shots?

Shari

Hello everyone! My son was a preemie so my doctor wants me to start taking progesterone shots starting at 16 weeks.

Has anyone had these before? Are there any side effects? Also how long after you stopped getting the shot did you go into labor?

The specialist said there are no side effects but I like to hear from people who have actually had to get them.

Thanks so much for your guys help!
