Has anyone experienced breakthrough bleeding??  I started to spot (sorry for the TMI, but it was brown) a little this evening, but only found out I was pregnant a couple days ago.  I've had random light cramping for a few days and thought I was going to get my period before the positive blood test. I'm hoping it's not a miscarriage, but my boobs don't hurt as much either. They still feel bigger, but not painful like the other day. I don't know if I'm losing my mind or possibly losing a pregnancy and it's driving me nuts. After spending way too much time on Google with my symptoms, I kept getting breakthrough bleeding coming up online and didn't know if anyone else had that before and what it was like. Thanks in advance.
