Painful ovulation

lex

I’ve never been like this until I had my son. After I had my son and when my first cycle came back it started. Every month when I ovulate my stomach cramps until I ovulate. It usually starts hurting 3 days before. Sex is painful. Basically just cramps until I’m ovulating and then my stomach cramps really bad when I actually ovulate. Does anyone know what this is or why it started after I had my son?

It’s been happening for almost a year now
