(NSFW) Should I be worried?

I need help. I had sex with my boyfriend a few days ago. And the thing is, I didn’t allow him to use condoms and I had no birth control. I know that sounds stupid if I was worried…but when I’m lost in a moment…I forget about everthing and then worry later. He didn’t “end” inside me…but is there any chance I may be pregnant? I know its only been a week…and I should wait for my period…but I’m really paranoid. I don’t know what to do…I’m kinda scared. This probably sounds silly though.
