Questions, Concerns!

Does my hymen need to break in order to get pregnant, my boyfriend and I where about to have sex (aka I’m still a virgin) but he didn’t put it all way inside of me cause I stopped him cause I felt like I wasn’t ready. My main concern is that he wasn’t wearing a condom and this occurred on Valentine’s Day 4 days before my period cycle is going to start.

Should I be concerned? Is there any chance of pregnancy? If so want actions should take? I just want to double make sure and take a action cause this is going to cause anxiety and worries lmaoo but please I need answers!
