I sat at 3cm 80% effaced for a month... Cervical checks are just mean. 

I was 1cm for 4 weeks 😂

It depends on your body. My sister never dilate, until the moment she goes in to labor. She has 7 kids. I on the other hand always dilate I was 3 for two weeks.

You could be 1cm for another month, or you could wake up tomorrow in active labor. All having your cervix checked can tell you is how dilated it is RIGHT then.
