Cramps when ovulating?

Hi ladies I'm new to the Glow community. I was wondering if it's normal to have cramps when ovulating. I'm not sure if I am, or am going to . This is supposedly my fertile wk, according to the app. I've been having mild cramps for the past 3 /4 days. The only time I ever really cramp is right before my period but that doesnt come around till almost the end of the month.
