Hi,
Welcome to ehealthforum,
The symptoms could be attributed to the hormonal changes, dehydration, anemia, etc. If the symptoms have been persistent for a few menstrual cycles, you should consider visiting your doctor/gynecologist for further evaluation to look for the underlying cause. Get started on treatment as appropriate (based on examination findings and investigations results). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest.
Take care.
