Help! Where’s my cervix?? 🤦🏾‍♀️

I’ve been trying to find my cervix and I’m sure I’ve found it..I have to stick my entire middle finger up there to find it and it feels soft and I feel an opening, that’s a little but rigged not super rigged tho but there’s an opening that I’m sure I can stick the tip of my little finger (not gonna try it tho lol). But then, I reached a taaad bit to the side of that and hit something harder..could that be my actual cervix? Or is that just something else ? I have no idea I’m so clueless lol. There was no opening or anything it felt like hitting the edge of your back gum located by your molars. Does anyone have any clue what’s going on?

I ovulated a week ago October 30th and have my period scheduled for November 13 (one week). My CM is egg white/watery and slightly milky looking.

New to TTC and this app :) any help is appreciated!
