Cervix, first time checking

Sooo I have a lot of signs of pregnancy, af isn't due till the first.  While analyzing every other possible way I decided to check the ol cervix.  I felt what seemed like a round bulb/ball of some sort.... Very high... A little tmi but I really had to try.  I would say firm but cannot distinguish if is a nose or chin?? Also just below that was what I guess as the opening.... Idk it was spongy and soft.... Any thoughts on if it sounds like I was doing this right or any thoughts in general about my findings??? I really appreciate the input this tww is making my coocoo ???? Thx!
