Basically me complaining

I was pregnant last year. My last period before pregnancy was December 5,2018. My first positive pregnancy test was 1/29/19. My son was stillborn 10/4/19. My first period was December 4, 2020. And I was 12 days late for my January period. So I got hopeful and thought maybe it’s all syncing. Maybe I’m pregnant. I take a test and it’s negative. But last year I had to take a test every weekend on January before I got my positive. So I figured it’s the same thing. I have sex and it induced my period. I’m equally livid and disappointed. I’m annoyed and glad it’s my day off bc I know I would be harsh to my employees today.
