Dizziness can be normal, it could be your blood pressure or just the extra volume of blood rushing to your head when you get up suddenly (you have lots of extra blood atm!). You could also be coming down with something.

Do you have any other symptoms like swelling or a headache? If so, contact your Dr straight away.

If it is really concerning you though, definitely call your Dr, even just for reassurance. I hope it passes soon.
