Glenda • Engaged Sept 2016💍 happy mommietobe 👼👪

I had my second hcg levels today they came back from 3700 to in 5000s my progesterone was a 13.5 which is still normal 12-20 range my doctor says it’s fine but they will like to see it at between 15 and 20 so he prescribe me the progesterone suppositories 200 mg I have to put in my vag. Has anyone takin progesterone sup. If so did it really stop a miscarriage?! Btw I’m not spotting or nothing they just put me on this because they want my level higher.
