It doesn't feel real.

Nikki • Stage IV Endometriosis Fighter. Daughter was born on New Year’s eve Pregnant with baby #2
I have 20 days left and it doesn't feel real at all. I can't believe she'll be here soon. I went to the doctor yesterday & I'm technically 37 weeks, but she's measuring a week behind. Anyone else have this? My doctor doesn't seem worried at all, but I'm just curious. I am very petite 100lbs pre pregnancy and I've gained 30lbs so far.
