Im bleeding in between period which isnt normal for me. But that's not my question ....has anyone one ever had huge half dollar size clots that are black? I usually have some very small clots on my heaviest which is day 2 but this is day 4 kinda heavy with big clots. My period are only 5 days and im supposed to have a normal 28 day cycle but this month has been different I had a 19 day cycle.
