I had an ear infection early on with DD2. Every time I moved my head I felt like I was on the sea!! No pain at all.
I have also had dizziness, however, this preg being the worst. But only when I move to fast from sitting / lying down etc
Might be worth a check from your Doc, just in case it is something they can help with as extreme dizziness could be dangerous, not in itself but what situations may arise because of it
Hope it goes away really soon, take care
