2cm dilated and 50% effaced at 35 1/2 weeks

Danielle
As the title says, I had my midwife app and I asked her to check me due to lots of pressure and contractions. I am 2cm dialated and 50% effaced. This is my 3rd pregnancy and with my other two I was basically closed until the end. I really think they are slightly off on my due date (January 30). I have also been measuring 3-4 weeks ahead consistently. Today I measured at 38 weeks.  I'm hoping this means I'll deliver sooner! Did anyone dilate this early?? When did you deliever?
