My period began at 23rd/24th of May and the bleeding usually lasts for a week. I had unprotected sex a few days (around 2-3) after my period. My partner just stayed in my vagina for a few seconds and I asked him to remove his penis. This happened for a few days. I had sex unprotected again today, but my period calculator says that I'm ovulating. Am I at risk? (I have no idea if he had pre-cum or not. He did cum when his penis was already outside.) My periods have been regular and consistent as far as the dates are concerned, and I'm expecting it to come by the end (or towards the end) of this month.
