Confused

Tly
So I went on a search for information. My cervix was low for a week and when I checked it today it was very high. Almost couldn't reach it. I read that the position of the cervix doesn't matter and that we shouldn't be checking it. This was on a md site. Has anyone had the same findings and also has anyone has the same experience with their cervix rising up?  Been ttc for 3 months. Af is due in two days.
