Head spinning

Amanda
I am currently about 6-8 weeks pregnant (used clomid 100mg this pregnancy ) I go to the doctor tomorrow for my initial consultation with the nurse. I don't think I will get an u/s or see the doctor. My head has been spinning constantly for about 5 days. It's horrible when I was pregnant with my other two babies I didn't experience this until later in pregnancy and it was only every now and then. This time my head seems like it's spinning 90% of the time and my nipples/boobs are on fire! Is this normal or could this possibly be a multiple pregnancy with my hormones going crazy? Any advice would be helpful. I'm not dehydrated or anything so don't know why this is happening so soon.
