Cervix at opening of vagina?

Im 36 weeks and decided to start the perineal massages... on the floor in front of my mirror so i could see what i was doing. I had to stop though because i noticed my cervix is literally RIGHT THERE just behind the opening of my vagina!!!! Freaked me out! I can totally see it if i open myself up a little but. I go to the dr tomorrow and will bring it up obviously but is this normal or happened to anyone?
