Ovulating?

I'm currently in my fertile window, glow predicts ovulation on the 7th. I've been using opks the last three afternoons and I see a faint line that may or may not be getting darker. This evening I keep feeling slight cramps but only on my right side. I just recently went off the pill, so I'm super new to this. Would I be right in assuming that I might ovulate in the next couple of days? Or am I crazy?
