Crease on back of cervix

I was checking my cervix like usual and I was sitting straight up and I felt like a crease on the back half of my cervix. Never felt it before. But if I lay down and feel my cervix, my cervix is up too high and I can barely feel the tip. I have no idea what it is. When I google it it talks about dilation and labor which I'm obviously not going thru. I ovulated 7 days ago idk if that has anything to do with it but please give me some insight ladies. I'm kinda freaking out
