So besides the one incident last night, nothing. It was there and gone right away. I spoke to my OB/GYN's nurse this morning, and she said that because I am between 5 and 6 weeks pregnant, it could be implantation (I always though that was at 10 days or so past fertilization). She also said it could be a blood vessel burst in the cervix or alot of different things. Even though it was bright red, she said it happens alot, and the fact that there were no clots at all, and it was just one incident (it was more than spotting, but not super heavy), Plus still only very mild cramping is good and, I should try not to worry to much. Unfortunately I have to wait until thursday, and the U/S should at least let me know if this is viable. I am trying to stay calm, but this is going to be a horrible 4 days. I am really freaked out.
