I had unprotected sex with a friend 4 days ago. i wasnt thinking and we didnt use condom and im not on any bc, he pulled out but not sure if any precum stayed inside of me, usually my cycle lasts around 30 days depending, and this last time it was a 39 day cycle my period was oct 18 and it lasted 5 days, usually only last 4 days, so im wondering if i could be pregnant? i was supposed to get my period yesterday but hasnt arrived yet, yesterday i felt cramping and there was light pink discharge once when i wiped, today no cramping only pinkish discharge. he is a family friend and were just having fun, i have 2 kids already with a crazy ex and im not ready to have anymore right now
