First time!! Please help

So I had sex for the first time last night and it was good and we used a condom that came with lubricant in it and its expiration date is in 2020 and right when he was about to finish he pulled out and by then the sperm was in the condom. Since it was my first time and I’m not on birth control once I got home I kinda freaked out and the next morning I bought plan B and took it just to be sure. I’m just wondering if there’s anyway I can be pregnant??
