Dilation

I am fully aware of cleanliness and the worry of injury so my doctors office doesnt do checks but im extremely uncomfortable and wondering where im at. Ive had sparatic contactions and my daughter is pushing down really hard on my cervix. Has anyone mastered checking themselves for dilation and effacement?

Dont bother with the dont do it i just want actual women telling me how they were able to and what to look for.

If you know other ways of knowing without internal let me know. Im 38 weeks my doctor said any time now.
