so this a TMI alert but hoping someone can explain my cervix

ive never tried to find my cervix before
one- i didnt know you could find it yourself
but today i tried
right away i felt the buldge of his head and as i slid my fingers higher it got softer and musher with mucous (like extremly soft)
now im not sure if i found my cervix or not
but my fingers went higher then his head which was at the back
now is that normal at 37 weeks or is my body gearing up for labour
does it make sense??? sorry if it doesnt
