Mothers, how quickly did you dilate?

I just came back from an OB appointment. Apparently, I’m already 2cm dilated.

I’m not exactly sure what that means. I was induced with my first pregnancy. So I’m unfamiliar with a natural timeline or what your body will naturally do on its own.

How quickly (or slowly) did you progress once you started to dilate?

Additional info:
– 37 weeks and 3 days
– second pregnancy
– baby has already dropped
– baby’s head has been engaged

Also…OB scheduled next appointment one week out. Does that mean that he thinks it’ll take longer than one week to get fully (10cm) dilated?
