Lost appetite

Danielle • Mommy to a precious little boy born 12/17/15 and full time working mom! I love my little family!
I'm 35+6 today. I have completely lost my appetite    I used to get hungry every 2 hours and now I have to make myself eat when I'm not hungry. I also have they dull, low constant stomach cramp and low back ache. Anyone else feeling the same way? I have an OB appt at 315 today. Hoping they can give me some info on his position, size, etc.
