am I pregnant?

I have sex with my boyfriend like any other 17 year old but we usually start unprotected and then he puts on a condom later he only finishes when he wears a condom and pulls out while wearing condom as well I was supposed to get my period 4/17 and I still have not gotten it I'm never late but I do have my usual period symptoms of bloating gas and swollen/sore boobs can someone help me understand if I should be worried or if I need to relax it will come ❤
