What 😳 TMI

My boyfriend & I had unprotected  sex like a whole week while I was "ovulating" according to eve . He came inside of me every time , 3 times a day for a week . & I wasn't expecting a period thinking i would get pregnant . Every pregnancy test came back negative, & I got my period yesterday - um is this possible ?? How is it possible , I was sure I would get pregnant at least that's what I thought ! Mind boggling 🤓
