I’ve always “checked” my own cervix

Whether it be during my cycle to see how high/low I am etc

I hadn’t felt the need to check it during pregnancy because things have been doing well

But recently I’ve been checking because i feel pressure down there.

The thing is, is my cervix is SO high it’s hard to reach, but I have been able to reach it a couple of times for the past week or two and can tell it’s open, I just can’t tell HOW open it is (except for at least to a 1) or if I’m dilating more

I normally either sit on the toilet to check, or will put one foot up on the bathtub and try to reach that way.

Is there a better way to check?
