Okay so i had sex with a guy in august, very late in august. I'm on the pill so we didn't use a condom. Everything was fine until i started freaking out because i thought i was pregnant. I took 3 pregnancy tests and they were all negative but my period was like 4-5 days late but eventually i got them and i only had them for like 4 days. I continued taking the pill after that and i didn't have sex during this time. I took the last pill on september 30th, now it's october 3rd and i haven't gotten them yet. idk i started freaking out again because i thought i was pregnant but i've had my period since the last time i had sex. Is there like NO chance i'm pregnant or what?
