Scared after miscarriage

LeeAnna
I am through the roof excited about my BFP but at the same time I am always worried about miscarriage. I had a miscarriage in November and had not even known I was pregnant, wasn't trying. My fiancé and I started trying this month using metformin and progesterone because I have PCOS and endometriosis. And I got a BFP on Valentine's Day. But I want to take a test every day just to make sure. I am so paranoid that something is going to happen to this baby. Any advice?
