15 weeks and only gained 6 lbs.

M • Mommy to the cutest 2yo boy! Now we have twins on the way!
With my son, I gained weight like a champ. Now with twins, I have only gained 6lbs. I had horrible morning sickness in the beginning but once that subsided, my appetite never really got back. Now I am a little worried. By now, I should have gained 19-22lbs.
