No dilation, "very" soft, but just lost mucus plug??

Doctor's yesterday at 2 p.m. --> not dilated, but "very soft/ready" cervix and she noted that my pelvis has certainly "shifted open."

But then this morning, I lost my mucus plug. Aren't you usually dilated before this happens? I know a mucus plug is a very loose indicator of labor to come soon and could mean another 2-3 weeks before anything really starts. But, thoughts and stories?? Please share! I'd really like to hold out at least until Monday!
