am I pregnant?

me and my boyfriend don’t use any protection when we have sex. Like EVER. We’ve been dating for about of year but he pulls out every time to finish. the other week he accidentally came in me on a drunk night. Mind you, this was 4 days before ovulation. my periods not due for another 7 days but I’m worried I might be pregnant. I’m 19 years old in college and have strict religious parents who would literally kill me😭😭 idk if im being superstitious but I just have an incline that I’m pregnant. Is there any way to tell before my period is due??
