Cervix question?

Chelsey
I feel silly asking this but I'm clueless. I understand how to tell if your uterus is high or low but how in the world do you tell if it's open? Like is it suppose to be wider slit or actually open open and stick your finger in it? I felt my cervix last night and it soft and high but idk how to check if it's open. I feel dumb 😫
