Already dilating?

Im already dilated to "almost a 2" anyone else told this? My dr doesnt seem worried. I know you can be dilated for a long time before you go into labor. Ill be 25weeks Sunday. With my son I didnt dilate at all untill 36hrs after contractions started. And then it took another 24hrs to get to a 5 😮 so I'm not complaining. Just a bit taken back..
