Vertigo 🤷🏼‍♀️😣

I’m 38+3 weeks today and yesterday evening I started feeling dizzy and nauseous, as well as started feeling small contractions. They were different from bh and had just a little pain with them so I know. They never got regular or anything and I had a few during the night. This morning it’s not contractions just yet but I am still dizzy and nauseous 😕 I’m trying to drink as much water as I can stand for now and may go to Walmart to check my bp but can anyone share similar experiences?

I should add, I started taking robitussin yesterday for congestion if that means anything
