Not gaining enough weight?

Hi,

So my doctor is concerned that I’m not gaining weight. I’m also pregnant with twins, just started my second trimester.

I’ve been maintaining the same weight. I think in total I only gained 5 pounds since I found out. I don’t have constant puking and I do try to eat as much as possible.

Does anyone think this will be a concern for the babies?

I told my doctor that I eat, I’m not a snack person either I like meals. But she told me I SHOULD be gaining weight so now I’ve been weighing myself every day and it’s making me anxious.
