Cervix tracking method

So I've started this cycle tracking my cervix as well as BBT and CM. The last couple of days I've noticed a bump, for lack of a better description, towards my stomach side of it. Had my husband feel this morning(sorry for the TMI) and said it feels like where the muscles all come together. Other than this one spot the rest of it does feel a little higher and softer. 
​Suggestions? Opinions?
