My last period was on 10th september and ended 16, had sex on 2nd october which was on 23 days of my cycle but he didn't ejaculate inside me or near my vagina. I was supposed to have my period on 8th october but i'm two days late, and no symptoms of pregnancy, I try the home pregnancy test both the salt, sugar and vinegar but still negative results, are they even accurate? I drink coca the next days on a empty stomach before eating, iiate papaya for two days but still didn't get my period. Please help I don't want to be pregnant. Can you figure what the problem is?
