Cycle outta wack

So I’m on the pill and I take it really well. Me and boyfriend have sex but this month has been rough so we haven’t really been doing it all and that’s okay. Anywho I’ve been on antibiotics at one point this month etc. we’ve used condoms every time except once and pulled out each time. Anyway I’m kinda late ish not really on my period and I test and I’m not pregnant. Should I worry or just wait it out.
