Scared for no reason

Hey guys! I had sex for the second time since I lost my virginity a year ago. It was this Sunday and we used a male condom. He didn't pull out, but there seemed to be no breaks in the condom. What I didn't realize is when we were cuddling after he went in with the very tip and had taken the condom off by then and I didn't realize it. What are the chances of pregnancy from this situation? I'm probably worrying for no reason, and I'm trying to be chill about it so I don't delay my period. eve says I was supposed to start yesterday, but I haven't, but I'm not super regular as it is so I'm not to worried as long as it starts in the next week. If it doesn't what next steps should I take and how long do you have to wait for a pregnancy test to work? Attached a pic of my cycle if that helps. Also got a weird smell I've never gotten before the day after we had sex. Thanks for reading and any input would be great!
