My periods alway last 5 days and are every 28 days. Feb. I had a normal period, when it came time to ovulate my right ovary felt like it could explode. March 7 my period was supose to start, it didn't show up, so I took a test, it came up negative. On the 8th, i went to the bathroom and when I wiped I had a brownish mucusy smear, I was cramp, I went to bed and the next morning I woke up and spotted all day brownish mucusy stuff, Then the 10th I started with a med. flow and then the 11 I have very little light pink bleed and by the end of the day, it turned to brownish mucusy stuff again.. please help me, what could this be?
