Your experience with 10th percentile

Rachel • Di/di twin boys and one on the way👦🏻👦🏼👶🏼

I’m 35 weeks tomorrow and my twins were measuring at the 10th and 13th percentile at Monday’s ultrasound. I’m also 80% effaced and 3cm dilated. Doctor scheduled another ultrasound for Friday to check again. Anyone have a similar situation with their twins or even singleton? What week did you deliver? How long were they in NICU?
