I had sex October 17th and October 25th without protection..my period for the month of October was the 12th and 13th i don’t have irregular periods or miss periods. According to my app after I logged my period the 25th was in my fertile window. However that same day on the 25th i took an ovulation test and it was negative/ low…i don’t know if I should buy a test or just give it a few more days and then talk to my doctor about my missed period. Someone please help me!!🫶🏽
