Why do I cramp suddenly after ovulation?

So I'm confused. I feel when I ovulate every month, Mittleschmerz. This month I have been cramping like nuts during ovulation. According to glow I'm done ovulating for a few days now (3 days to be exact). Yesterday evening I started cramping again, which shouldn't be happening until a week or so before AF. Didn't have sex during my fertile window. Any thoughts of what is happening?
