I'm supposed to start progesterone in a few weeks. The ob I was going to wanted to start me on the pill but I've never had a miscarriage or an incompetent cervix. I've also researched that it's not as effective as the shot. Have you ladies asked your ob to be on the shot instead of the pills? I switched back t my other OB and I'm pretty confident they will be giving me the shot since I'll be going to a high risk ob.
