FTM question!

Chelsea

36 weeks! Not dilated, but cervix is moderately soft? And baby girls head is sitting on my pelvic bone. The doc wanted to do an emergency ultrasound due to my belly measuring 2 weeks behind and I haven't gained anymore weight. I was alone and needless to say, freaking out LOL! I called my husband ready to cry. Long story short, baby is healthy and wonderful, she is just a smaller girl like her Momma! She has a head full of hair also! However, she has dropped into position. So I'm curious as to when or if I will start dilating? Also, what's the difference between effaced and softening? I feel like they are similar? Thanks ladies!
