Pregnancy or PregNOTcy

I, F18, a few weeks ago, had a long make out sesh that ending with STUFF getting on my stomach and the groin, and my partner immediately fin*ring me with hands he just used to get himself off- without washing them off…

We immediately got into the shower and washed it off, but now, a few weeks later, I am experiencing lower abdominal pain, nausea every evening, extreme mood changes, frequent urination, back and shoulder pain, extreme jealousy and feeling horrible every time i eat or drink alcohol.

My mother has had Chocolate Cysts on her ovaries and my grandmother and aunty both have endometriosis so i was wondering if this could be something along these lines or could i be pregnant
