I don't want to sway anyone's opinion, but this was at 3 days late. My husband says he can't see anything. AF arrived tonight, serious cramps and blood clots. I just wonder if I could have been pregnant? If I was, do I need to go to the doctor or will my flow take care of things naturally? Any information will be helpful, it will take me at least 4 weeks to get in to see my doctor. Maybe longer since I just saw him and everything was great.
