Lots of little cysts could be PCOS, I can't remember if you already have that or not - the doctor who did my scan before my D&C said it looked like my girls were wearing their pearl necklaces

I don't think it's impossible for you to have gotten pregnant on this cycle. For me, the aching lasted one to two week after the actual burst. I think mine either take awhile to burst or I lose a few at a time, because I'll have 3 or 4 days of the extreme pain, can't stand straight, bowel problems and general hurtiness, then it'll die down and while it still hurts, it's nowhere near as bad y'know?
