1 cm dilated! Help!!!

Silvia

I'm 34 weeks 3 days pregnant with twin boys! I went to my appointment yesterday and the Dr said I was 1 cm dilated, my boys are almost 5 lbs each but my goal is to make it to 36 weeks! I have a 9 yr old I with him I went from 1-5 in 5 days, however I was more active than I am now. Any idea in how long it takes to dilate with twins?
