am I pregnant?

I was making out with my boyfriend a week or so ago and we started like touching each other and he pulled out his dick and asked if I wanted to do anal (I didn't have pants on at this point). I said no and he went to rub his dick against my vagina. it felt really good and he cum shotted me but I made sure to cover my vagina but I'm scared that it might have gotten me pregnant? I'm not supposed to get my period untill the beginning of February and I'm scared.
