Is this normal?

Hi guys, so today I’ve been getting little like bursts of dizziness. Not super dizzy but I can still feel it, if that makes sense. I drank coffee this morning and I’m not a big coffee drinker, maybe that could be it 🤷‍♀️ or I could possibly be dehydrated. I’m 31 weeks pregnant, so maybe it could also just be everything sitting against my nerves 🤷‍♀️. Has anyone else gone through this? It’s not like constant, it comes and goes in little bursts of dizziness.

EDIT: It could also be because I’ve started taking iron gummies, I’ve been taking how much is says on the bottle which is two but I think I really only need to take one because my OB says I’m only the tiniest bit of anemic so maybe the iron gummies raised my blood pressure too much and that’s why I’m getting the dizziness. I don’t have any pain and my baby moves around like crazy.
