This happened May 18, 2012 when I was 4 DPO on a 23 CD window, I ovulated on the 14th. May 15-17th; I've had diarrhea, I was exhausted, and had cramps. It started out as light, than dark red with small and big clots passing down, during those days (May 15-18) my boobs were heavy, my nipples were sensitive and they were hurting, and I have blue veins around my areola, I was exhausted even today, my symptoms are gone except the exhaustion and blue veins stayed, and I'm having mild cramps. My actual period comes May 27. My "period" begin at 4 DPO until 9 DPO. can IB come early and last 6 days; sounds wrong for me, usually 6 days is a period. Is that possible or not? I'm not stressing out or anything.
