Could I be pregnant?

Two nights ago (Sunday) I forgot to take my last active pill in my pack. I took it Monday morning when I remembered, then later on Monday I hooked up with someone. He used a condom but by the end it was only halfway on. Since I missed the day of birth control and the condom had partially slipped off, is it more likely I’d be pregnant?? also, according to tracking cycle, last night was a 27% I’d get pregnant if I wasn’t on birth control which kinda freaks me out since I missed that one day. Help!!!
