So the last time i had sex was the last week of march once. We used a condom and i am positive it didnt break because nothing leaked and i made him fill it up with water to check after, i didnt see him put the water but u believe him. The next month, april, i got my period like a day late but i still got it. It was just like my other periods, it leaked through my pants and everything like always. Now this month its late by 3 days so far and im just a little worried because women can be pregnant and still get their periods the first 2 months I believe and you never know if a sperm just slipped by. But my friends and i have our periods synced and none of us have gotten our periods so idk if i could be pregnant which i dont think but perhaps. Or maybe im just a little late. Also my boobs are sore and ive been having cramps.
