Cramps during ovulation?

Brittany

Using opk’s and this cycle I got one day of high and today my peak, much sooner than previous months. Yesterday afternoon during a nap I was woken up by cramps. And tonight they are pretty obnoxious. Is this normal for ovulation? I guess I never noticed before when I was on b/c. I’m not one to get cramps ever so when I do it’s weird
