I started my period on the 18th and it ended around the 22nd. I have an IUD, but stuipidly spent $35 to take ECP on the 16th to try and postpone my period. Didn't work, but that's neither here nor there. I also had some pretty rough sex on Sunday where he bumped my cervix quite a bit.
Anyway. I just went to the bathroom today and there is some bright red bleeding. There was a little bit of (TMI) uterine lining on the toilet paper when I wiped, which was kinda weird. I usually get a little bit of spotting when I ovulate, but that 1) shouldn't be for another week, and 2) is never bright red.
