Cramps

I'm TTC with my husband and this is the first cycle we are using PreSeed, we've been using it all throughout my fertile window and today is my ovulation day. All day yesterday and today I've been having weird stomach cramps, sometimes by my uterus but sometimes up more towards my sternum. Is it just because I'm ovulating do you think? I'm probably just overthinking it but I usually don't get cramps like this until my period.

Update: it's the next day, and I'm still having some cramps but now my boobs are also sore. UGH I wish I could have some answers!
