Pain in stomach.

Nadia • Mommy to beautiful twin boys, Dominic and Roman 💙💙
What do ovulation pains feel like? I'm having this pain in my stomach right after my SO and I had intercorse. It kinda feels like a Charlie horse and hurts more whenever exhale. 
I know it's not cramps because my period isn't for another 3 weeks. I also just got the birth control nexplanon, maybe that could be the sorce? 
Please someone help );
