sorry for the picture!!

2 weeks ago I had what I thought was my period it lasted 4 days on and off. started out a thick brownish color then turned to this peachy color after the 3rd day but had no signs AF was coming!

here it is day 2 (2 weeks later) and I still have no menstrual cramps or tender boobs like usual and I always have severe cramps the firstt day of my period. usually there's a lot of clotting. I'm just confused though because my chart says I should have been ovulating and I did have unprotected sex but it being day 2 shouldn't my period be bright red with clotting and not just a dark pinkish color?
