Help please!

Allison • Mommy to Paisleigh Nicole.🌸

Okay so, i went to the doctor yesterday. He said my sugar was almost nothing, and thats why I've been looking pale, getting dizzy, and feeling quite weak. He said for me to eat 3-6 meals a day. I do already. Fruit for breakfast, Sand which for lunch, and usually meat with vegetables for supper. I've stayed away from eating junk food BC all I've heard is "Thats not good for the baby, you dont need to eat that.". Everything the doctor told me to do, I've been doing. But this Is where im a little worried. My Baby girl is 29+3(as of yesterday), she's measuring 26w. The doctor said I have to get my sugar up so she can gain the weight she needs. Ive not gained any weight through out pregnancy, but now its a problem I guess. I need advice. I don't know what to do or what to eat or how to gain weight. I often get sick eating fat food.
