Am I Pregnant?

Abigail
A week after my 15th birthday i lost my virginity in a car, I had protected sex with a guy from my school who's a junior and he's 18. I think the condom broke but I don't really know for sure, I would ask him but he's avoiding me, blocked me on all social media, and just won't talk to me. He's told a lot of people at our school that we had sex and it's kind of making my emotions go every where when they're normally pretty controlled because I take medications. Recently, my stomached been upset, tender breasts, diarea but not throwing up yet, and I've been on a roller coaster of emotions this last week. My parents just found out about it from my pastor because the word had gotten around and now they're taking me to the doctor for an STD test, should I also get a pregnancy test? My parents are also extremely religious and found out that I also have feelings for girls, how should I talk to them about it?
