Hi,
Thank you for posting your query.
It is possible that you have menstrual 
migraine, where symptoms such as headache, 
dizziness, etc occur in close association to menstrual cycles.
You would benefit from migraine preventive medications. Please 
consult a neurologist. 
Please get back if you require any additional information.
Best wishes,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
