I had sex about 5 days ago (with condom + pulling out; however, condom did not fit correctly and slid a little bit without ever coming all the way off. I made sure the condom didn’t break after sex, too). According to this app, my fertile window ended 2-3 days before I had sex. Starting yesterday morning (4 days after sex), I had some dark brown blood. This continued for 2/3 of the day, then it became bright red, normal period color blood for about a day. Not super heavy, but filled about 1/4 of my diva cup over night. I’m not supposed to start my period for another week! I’m scared. What do you all think? Thanks
