Does anyone have experience with breastfeeding while pregnant?

My supply dropped down, so my 8 mo daughter went from nursing every 3-4 hours to every 1-2 hours.

Now, I also get nauseous when I nurse which has never happened before.

I’m also worried that my caloric intake is too low to both grow and feed a baby - I’ve been losing a pound a day this past week. (It’s so hard to eat with morning sickness when I don’t have an appetite.)

I wanted to nurse until my baby weaned herself (and maybe this just speeds that process up.)

Anyway, any advice is much appreciated!
