What is going on?


Ok so i had unprotected sex and the next day I started with my period which was 11 days early that has never happened to me before. I did a couple pregnancy tests and they came back negative.Do you know what that could mean? Also Then I had unprotected sex twice the day before and once the day of ovulation which was July 7 & 8. I just want someone's opinion, how many of you think I'm pregnant? And how long should I wait to do another pregnancy test??
