Cramps - pretty normal, but if really painful or bleeding, speak to dr
Dizziness - I got this too. I found I wasn't eating enough salt - so I added a bit more to my diet, not heaps though. I also ate every 2 hrs at a min and that helped out as well.
I got dizzy with low blood pressure and low iron. Try eating more red meat and also to help with the absorption of iron into your blood you will need to increase your Vit C, so also eat more citrus (mandarins are my fav at the moment!) and drink plenty of good OJ.
If it gets to the point of getting in the way of your normal activity then maybe just ring up your GP/OB/MW and ask - you might need to have your BP and iron tested.
I had cramps at 8 weeks with my first two pregnancys just keep an eye out for any bleeding. Then c your dr :O)
I also had bad dizzyness with my first pregnancy. It was high blood pressure which is really important to keep an eye on. Next time your at the Dr or OB I'd get them to check it.
