Paranoid

So I had sex for the first time last night and I feel I’m just being over paranoid. I made him put on a condom and I’m on birth control but this was v unplanned so I wasn’t taking my bc at the same time every day but it wasn’t a drastic change in hours ( for example I take it at 7 every night but maybe forgot and took it at 8-830) and after I checked the condom for any rips and didn’t find any and my periods suppose to be in like 4 days there’s really no questions here ahah but I guess I’m asking chances of pregnancy?
