I have been noticing cramping in both of my ovaries, a couple nights ago it was mainly the right one, and now I can definitely feel both are cramping. I generally have 43 day cycles, (After CD 28 if I didn't ovulate, my OB prescribes me 10 days of Progesterone so I can get a period, otherwise, who knows if/when I would get my next period). Do you think it could be implantation cramping? What does that generally feel like?
