Can we drink nectar protein?

I am right at 4 months pregnant I found out at 9 months post op. I had the vertical sleeve and I am eating a little more. I am so afraid of gaining my weight back and while I enjoy the eggs and bacon for breakfast I would like to know if I can drink my nectar protein instead? Can some one relate?

I drank them every so often when I was pregnant, only because nothing else would stay down for the first trimester.
