Cervix help🆘

Alright, ladies. I'm not ttc, however, I have had some odd symptoms the last few days. I'm trying to monitor my cervix. It's mid-high and soft, but I can't tell if my cervix is closed.

-I just came out of my fertile window.

-My body is incredibly hard to read because I have severe PCOS and I don't have regular periods.

- Not on BC because I can't adjust to the high hormones needed to control my PCOS.

-I did have a period this last cycle.

A- how does a closed cervix feel?

B- how soon would the cervix begin to show symptoms of conception?
