weird and scared

sooo.. I'm 17 right prime time for being sexual no biggie.. until I get a scare. my boyfriend and I had unprotected sex 2 times before this but this is the second scare I had and my period is supposed to come tomorrow but I'm literally flipping out reading symptoms of pregnancy I think I'm just scaring myself tbh.. he didn't cum inside me but I always get scared yanno. I had this mild pain in my right side 2 days ago and I never really noticed it before but no sore boobs or severe cramps just feel kinda worried..
