 [ Symptoms ] i had unprotected sex and he ejaculated inside of me it was three days after my period could i be pregnant no bc [ Disease ] hi yes you can get pregnant from having unprotected sex and that is a fact and for some unknown reason the odd women can get pregnant from having unprotected sex any time of the month its male sperm it can live inside the womb for a few days far longer than a female egg can and that is it your pregnant but on an outside chance you will have to see if you get your next period but even then still get a pregnancy test done do hope this helps you good luck
