Thanks for the query to H.C.M. Forum.
If I were your treating doctor for this dizziness
during 7th month of pregnancy
I would come up with following possibilities , these includes.
, diagnosis can be confirmed by examination of blood pressure as this is a most common cause of dizziness in pregnant woman .
2 Hypotension , diagnosis can be confirmed by measurement of blood pressure both lying and standing position as postural hypotension
is more prominent in pregnant woman.
3 Anemia again this is most common cause of dizziness so hemoglobin
level is important , so go for this examination.
Least chance of tension , if you think relax .
In my opinion you should consult a gynecologist and get his opinion at this stage.
Good luck. Dr. HET
