I need help. I'm super confused don't judge.

On October 9 I got my period and by the 14 of October she was gone. I waited and had sex on October 24-25 after ovulation. Then couple days later I started to bleed which was the 29 or 30 and lasted until November 4. And my period was due on the 6th of November so technically I'm 2 days late. I took a pregnancy test and came back negative.. is this normal or can I be pregnant. I'm worried. Please I need help
