Am I pregnant?

tori

I had unprotected sex on the last two days of ovulation. I am not on any form of birth control. He pulled out right before he finished both times and we made sure that he went pee before we did it to avoid Pre cum. I am 3 days late and I am normally early. I took a home pregnancy test last night and it came back negative right away. I still have not started my period and I’m starting to worry. Could I be pregnant?
