So I’m on day 21 in my cycle, which averages 35 days. Two days ago I had really, really bad pain on my right side. Nothing helped. I went to bed and it was gone by morning. Yesterday, I had dull, almost vague cramping on the underside of my tummy in the middle. I’ve been taking opks and they’re not getting darker at all. The apps say I should be ovulating around now. Any help???
