Pain in stomach after pp sex

First time we had sex, being that I’m cleared I’ve had some cramping in my stomach. We had sex 2x last night and I’m not sure why I’m so crampy. It didn’t hurt down there at all felt amazing actually. Just wondering if anyone else had some crampy feelings, could it also be that I haven’t used the restroom in a few days? Not posting for hate or smart comments genuinely curious and need advice .
