On Glow there is an option for where your cervix is.... I've been trying to feel my cervix for days now and I cannot do it!!! I've tried every single finger. I've laid down, sat on the toilet, squatted Nothing!!! I'm sorry if this is too descriptive I just need HELP!!! It's starting to really stress me out :( all I can feel is the walls! There is no feeling like a ball or nose or anything. I'm so frustrated! Please help. Pleaaase.
