Hi, last week on Friday (it's Thursday now) I had sex with my boyfriend. We don't quite remember when it happened, but at one point he looked down and the condom wasn't on anymore. I rolled to the side and it was next to / under me. We didn't continue having sex, and he told me he didn't cm in me. He did cm before and threw that condom away and put on a new one. He said he probably was in such a rush to put it on that he might've put it on inside out, which caused the slipping. We went to the pharmacy immediately to purchase emergency contraception. I took the pill that night. That was right before I was going to start my period. It was the 29th of January. My last period started on the 30th of December and went into the beginning of January, so I was expecting. Sometimes, my period is a few days late or early, though. So it didn't come, and I thought nothing of it. But now it's Thursday, and I still haven't gotten it. Should I be freaking out over this? We had sex the friday before last friday, the 22nd of January, and according to an app I have that tracks my period, I was ovulating. But, we used a condom and had no complications that night, so I don't know if that could've caused it. I am extremely stressed and I don't know if I should be. I read online that emergency contraception can cause early/late periods, but what if the period was supposed to start a day or two after taking the pill? How long should I wait?
