SUPPER SCARED BLOATED OR PREGNANT ????😯😯😯😯

So I went to go get my knee cleared from my injuries and my doctor said I had went up alot but I told him I hadn't really been eating . But my stomach keeps getting bigger my cousin who just had a baby said it looked like I was getting a pregnancy line I'm just really scared , . Yes I went to a party not to long ago and I guess they spiked the drinks because I was wasted and ended up having sex with a guy I've known own for a while. Please no negative comments I am so scared right now And parents think I'm a Virgin I'm not even allowed to date . I just really need help with this
