Not feeling well - has anyone else experienced this?

I’m 27 weeks pregnant with twins. It’s really difficult to describe how I’ve been feeling but I’m going to try. I feel fine when I wake up but shortly after getting up, I start to feel really bleh. This happens whether I eat breakfast or not.

Essentially I almost feel disoriented without feeling confused. Definitely a little lightheaded/dizzy, but not much. Its almost like feeling nauseous without the actual nausea.

My BP was 110/68 at my appointment the other day.

I’m anemic, but taking iron supplements.

I’m trying to drink as much water as I can, but I’m so bad at it so I wouldn’t rule out dehydration.

Any thoughts? Mostly I want to know if this is normal or if I should be worried.
