How to gain weight while pregnant!?

Hannah • This is my first child and my husband, Mishon and I are so excited!

OK ladies, I just got back from my appointment and baby girl weights 6pounfs and I'm measuring 1 week ahead, no biggie.

The big deal is, I've lost too much weight (50 pounds) and doctor wants me to gain weight like right away! So I need ideas on how to gain weight, any suggestions are welcome! I'm a FTM and am a little worried because apparently I'm losing weight because she is pulling fat from me instead of protein and apparently protein is what she needs for healthy brain development.

I need suggestions please! Thank you!
