Nervous

Ok so this is my first time writing up here and I really hope someone helps me... I'm 20 years old and I just recently lost my virginity about a month ago with this guy I've been seeing. No we aren't a couple.. pls don't judge. We're only seeing each other but we both wanna go with the flow. Anyway, I've been on birth control for about a year (I got on it for my cramps and acne) and in the beginning I wasn't always on top of it but about a month or two ago I've been taking it on time. Before I make this any longer, him and I had sex without a condom and both times he didn't pull out. Like I said I've been taking it on time well before him and I started having sex I still am. Is there a possibility that I can become pregnant? My period is suppose to start in two weeks but I just dunno if I can handle the anticipation.
