counting down to b-day

Went to the doctor on Thursday. She did an exam & says I'm 1cm dilated. I asked about effacement & she said that my cervix was still very thick. I guess that means 0 effacement? She also told me that she wants to do an ultrasound with next week's appointment to check on his size & position. I was surprised & very happy! I'm wondering if it has anything to do with me gaining 7 lbs in 1 week??? She didn't say & I didn't think to ask. She told me she'd be able to give me an approximate weight...which is so cool! I'm just happy that I get to see him & I have a time & date!
