What's the normal/average size of the cervix @ 20 weeks? Can braxton hicks contractions dilate, shorten, or efface it?

In brief: Cervix

At 20 weeks is a regular size cervix that is unaffected by braxton hicks contractions .
They are just practice contractions and nothing to be afraid of. They are normal !
