I'm not sure where to start..I just had my period 15 days ago and I do keep very good track of my cycle and my fertile days and ovulation cycle, so technically my period is not due for another 14 days. Me and my boyfriend had sex 3 days in a row (Fri,sat,sun)before my "fertile" days,(which began Monday) had no symptoms. Thursday, which was a day before my actual ovulation day I started spotting brownish, then pinkish blood. Enough to have to use panty liners. Yesterday (Friday) was my actual ovulation day the spotting increased to a light period flow and is brick red, still bleeding today(Saturday), now enough for a tampon. I've read up on implantation bleeding but that usually occurs a week or more after ovulating , not while ovulating. I'm so confused. Have had 3 successful pregnancies and this has never happened before. Another thing is my period last month(2 weeks ago) only last 4 days which is normally 5-6. I have been on birth control the last couple months, could that be throwing things off this much? Please help! Just trying to gain some insight on this and wondering if anyone else has experienced something similar?
