I'm in the same predicament as you. My cycle is 28 days, with my period lasting 5 days. My period started July 13th. My husband and I had unprotected sex on July 26th. I�ve had dull cramps since July 30th. On July 31st in the evening, when I wiped I had red blood mixed in with clear discharge. August 01st I woke up with a tiny bit of brown blood in my underwear, and all day I�ve had pink & brownish coloured blood when I wipe. I�m still having dull cramps. I�ve read that implantation bleeding can occur anywhere from 6 � 12 days after ovulation. I'm wondering if it's too soon for implantation bleeding to occur since it's only been six days since ovulation? But the last couple of months I have been spotting in between cycles due to alot of stress at work. I know it�s stress related because I spotted for a few months leading up to my wedding and then it stopped. This time around though, the spotting is different because of the cramping associated with it. Also, when I was spotting before I never had red or pink blood it was always old blood that was brown. I guess I�m overanalyzing because I just want to know whether or not I�m PG. My period is due August 10th. I bought a home pregnancy test (double pack!) which I will do five before on August 5th. Please keep me posted on what happens and I�ll do the same!
