Progesterone??

Liza • 👦🏻 5/5/16 👼 8/13/18 🌈 👶🏻 12/15/19 👧 12/4/2019 (our 🌈 baby came early) 🤰with baby number 3

So, I was 10 days late on af- took a blood test, came back negative for pregnancy, but dr. Put me on Progesterone to have my period start again. Has this ever happened to anyone? We had a miscarriage this last August- but cycles went back to normal- and then suddenly no period this month. So confusing!
