Some advice for a first timer?

Hi, all of the wonderful ladies of this community! I was hoping to get a little bit of expertise in a world that I'm definitely new in. I'm 17 and had my first time with my boyfriend recently. We were both ready for it and everything about it was really wonderful and we enjoyed it together. He used a condom which stayed intact and I was in the middle of my period. My period ends the 28th and my ovulation cycle begins November 8th. I know I need to be ovulating to be pregnant, so this question may seem a bit dumb, but is there any chance at all that I could be pregnant? I know there's always a chance if a penis was in a vagina, but realistically, is the risk high? Please only kind words, I'm really new to this whole topic, yes, but I stand by my decision :)
