Pain but clear ? Help

So I went to my doctors and had a pelvic exam and everything was clear and we did other test as well (blood,urine) and they ended up being clear. I have a sore/ cramp pain in my lower abdomen and pelvic area, Idk why? I haven’t exercised so not that...

I was a virgin about a month ago and my bf and I have been sexually active and it hurts when I have sex, unless he goes slow idk if that has anything to do with it.

But I’m scared of endometriosis or anything like that!!! Has anyone else experienced pain like this? PLEASE Help!
