I need help to calm my nerves. First off I had sex with my close friend of mine. Condom kept slipping off but he was dry no precum. Fast forward, we had sex again the other night and this time the condom broke and he said there were no pre-cum. So the next day I went to the nearest store and got "Take Action" and took it around 7:30ish am. Now with my period it hasn't come yet I've missed two days of it but at the same time, I don't know the cycle length from the last first day of my period until the next. It's weird but I just need advice because I've been very stress these past two months and crying and feeling like shit.
