I had cramping today (well now it's yesterday), kind of a dull cramp on my right side. What could cause this? I am still spotting from AF. I obviously don't think it is ovulation cramps, that shouldn't happen until around CD 15.
Normally my AF cramps are only on CD1 and they are not localized on one side.
The only thing I can think is a cyst? But I have never (to my knowledge) had a cyst.
Also is it bad in any way that my AF lasts so long? Like this month 6 days long plus 2 days of spotting. I've always tended to have longer AFs, but I wonder if maybe it is bad for my uterine lining in some way?
I am not amused by my body right now.

It's bugging me that I don't know why I have these cramps.
