Hmm, I spotted for 1 1/2 weeks missed a few days, got really excited thinking it was over, did some exercise and then started bleeding again, spotted for about a week that time, got AF 2 1/2 weeks after that, so all up 6 weeks. It's so hard to say what's normal after a m/c, practically everything is! Basically, if your not in pain and not passing smelly clots, then your ok. I heard that your hcg level had to be 0 for 20 days in order to O, and then AF came 14 days after that. But I have no idea how accurate that is! It might be AF, it might be O spotting, it might be implantation spotting, or it might just be WTF spotting. Sorry for the lack of actual help! xo
