First, I have three healthy children and I've had two miscarriages. About two weeks ago, I had an hcg blood test that was inconclusive. I bought the digi home prego test that says "pregnant" or "not pregnant." I took one on a Thursday that came out negative and the other on Saturday that came out positive. I got the digi kind so I couldn't misread it. Monday I went to get another blood test which came out negative, confirmed by another negative on Friday. My last cycle was at the end of June, no spotting. Unless two blood tests are wrong I am not pregnant but I am curious what would cause my body to act as though it were. If I miscarried I would be bleeding already so I'm curious what could cause this situation. I would love either people with similar experience or medical experience to help with this one, it has me stumped. I've never had PCOS or endometreosis to my knowledge but could something like PCOS cause this?.
