Cervix position during a chemical

My cervix is super high and soft. I haven’t started bleeding yet, my tests were super faint for 2 days and then I got negatives after that. I’m 13 dpo, my period would be due today. Every single month it’s the same thing, my cervix drops about 2 days before my period.

Now I know this is not the same case, that’s why I wonder if anyone here checked their cervix position after their tests got negative?

TIA!
