Dialated to 2 1/2 at 22 weeks with twins

I am currently 22 weeks 4 days pregnant with twins and last Saturday I went to the hospital due to contractions. Once I got there the contractions stopped. They checked me to see if my cervix was closed but it was dialated to 2 and a half. They flew me down to a hospital that is more equipped to care for babies so little if they decide to come. Long story short I haven't dialated anymore and contractions have stopped completely. My question is has any mommies experienced this and gone on to carry their babies for atleast 10 more weeks while being dialated??
