Agree with above, have someone you feel comfortable with check you, like your hubby. I think each finger is a cm or 2 so if he can fit one or two fingers thru your cervix then that's how many cm's your dialated. (I could be wrong) I agree with googling how to check it.
Google how to check your own cervix.
