32 weeks and already bigger than full term with my first child!
With my twin pregnancy, I was considered extra high risk simply because my first pregnancy was high risk. For that reason I was on a weekly shot to make sure I didn't dilate too early. At 32 weeks I was 2cm dilated anyway! Luckily they held out until 37 weeks with the help of some bed rest!- +++++++++++++++++++++++++
