You could be low on iron. They can check you for that. With my 2 pregnancies years ago I had to take iron pills 3 times a day and it helped with the dizziness.
I'm almost seventeen weeks and have had NO morning sickness whatsoever and as far as we know things are going swimmingly - good luck!
Hi. I have the same issue at 7 weeks. I think it's due to blood pressure dropping which happens right through til mid pregnancy, when it starts to increase again.
