i had protected sex 1 day before my ovulation (according to flo) and 3 days before my protected ovulation (according to eve). as of my knowledge the condom was okay and my partner pulled out before coming. now according to flo my period is due tomorrow and according to even it’s due 2 days later. regardless i haven’t had any of my usual symptoms like cramps still. i have only had sore breasts. can someone help me and tell me if i could be pregnant?
