I had sex a day after my period ended, and took the morning after pill 2 days later. My partner didn't cum in me; we stopped after a few seconds because I wanted us to get protection. We got the pill because I was worried about pre-cum. Now my period is late by a week and two days. I've taken the pill before, and it delayed my period by exactly a week back then. Should I be worried?
Also worth mentioning is that I've travelled before the time my period was about to start, and I also got sick. I've also been stressing out about the incident, so might these be factors that could delay my period?
