Low cervix

I’ll start by saying I did NOT check my cervix, I know that is not something for me to do.

I was on amoxicillin for a UTI and developed a yeast infection. My doc prescribed some cream for me to apply at night. This is my first yeast infection so I honestly hope I’m using the applicator correctly. It says to push the tube in as far as it will go. Well the first two nights the tube went in pretty far, up to the part where you hold it. But the last two nights I’ve felt resistance sooner, last night i felt resistance pretty low. I don’t need to stick my fingers up there to know that it was my cervix. I’m 26 weeks and this is my first pregnancy, is it supposed to be that low?
