Confused...8 almost 9 days late.

Candy

I had sex on Oct 16th. We used the pull out but after he pushed it back in...on Oct 29 I got what I assumed at the time was my period AND covid. I was suppose to start period on thanksgiving but nothing. Not even a spot. Now on my apps I should be going into my new fertile window but still no period. I'm 8 (9 days late at midnight). My boobs don't hurt. I have no food cravings. I have been sleeping a ton. So tired I'm taking naps thru the day and can't wait for bedtime at night. Nausea here and there but I just assumed all this was the after effects of covid. My period on Oct 29 lasted roughly 6 to 7 days total. (Usually only 4.) Started with brown blood and then went to light pink bleeding and would go between that and the brown discharge. Any input as to what might be going on is appreciated. I haven't tested because I don't believe its pregnancy related because of the period, pullout and no real symptoms.
