Dear eqmpn23
I hope you are well I am sorry to hear that you are havin g dizzy spells and cramping and I know that I am not an MD but I know that when my ex wife was pregnant with she had dizzy spells due to anemia (low blood pressure).
The best action is to ask your doctor when you see him it may just be that you need to have a course of iron tablets as for the cramping you will have to consult with the doctor if you haven't already done so!
Do let me know how you get on.
Kind Regards
