progesterone insufficiency
"I was prescribed progesterone in early pregnancy due to insufficiency. I switched pharmacies and this p-2 progesterone pill was a new brand that I was switched to. Two hours after taking the first pill (vaginally, as directed) I had spotting. This spotting continued for three days while I was on this pill. One day I didn't take it until the late afternoon and all morning had no bleeding. Then two hours after taking the pill I started bleeding again. I was far enough along in my pregnancy that when I brought this up to my doctor he said that I could safely stop taking it. Ever since I stopped taking this pill, the bleeding had since stopped too! I would not recommend this brand of progesterone."
