The last day of my last period was September 22, I had sex on October 15 and was supposed to get my period on the 17th. We used a condom and made sure it was put on correctly, after we even filled it with water to see if there were tears and there wasn't. I'm 17, please no lectures! But my periods have always been kind of irregular, some days they come as predicted but some months it'll come a week late or even up to 15 days early. I'm 13 days late now and I just started to have tender breasts. If my period tracker app is correct, then I wouldn't have been ovulating that day, but if my schedule wasn't accurate is there a chance I could have been ovulating? Please help!
