Progesterone suppositories

Katharine • Momma to my Rainbow baby boy💕
Anyone else on progesterone suppositories? My dr prescribed them to me today. The only reason I'm a little thrown off is to why she put me on them. She didn't check my progesterone levels, I was in last week and we saw the baby with a heartbeat at 6 weeks. Is it normal to prescribe the suppositories just because I'm considered high risk?? Anyone in a similar situation???
