Cervix position tmi

Rachael • I am 23 years old, I have been with my partner for almost 4 years in july 2015 and we are trying for our first child.
I think I might of felt my cervix for the first time today. I felt something just like a lip. Is that my cervix? Does that mean its open? I didnt feel anything else and I always thought it would like 2 lips? And it took a whole Index finger before I felt it does that mean its high?
