Hi Doc, We Had Sex Yesterday With My Boyfriend. I

Hi doc, we had sex yesterday with my boyfriend. I gave him a blowjob and then I didn't let him to cum that fast. After that I went on his top and I inserted his penis inside me, I do the up and down thing once and I pulled it. Is there any possibility that I might get pregnant? Anyway, my last menstruation happened last September 2016, I think that was on 1st or 2nd week. I can't recall. Am I still safe? Or I might getting pregnant?
