Hello dear
Understand your concern.
I think it is due to
hormonal imbalance due to sudden change in life style.
Elevate place has no relation with periods.
Following are the other causes
High level of stress, Late ovulation, Excessive exercise, Drugs: Birth control pills,
thyroid medication, Excessive tea and caffeine, Thyroid problem
Do regular walking and exercise.
Eat healthy diet
Also note that
Menstruation required co ordinate action of various hormone that secreted by ovary (
estrogen and
progesterone) and brain (FSH and LH).
If any above hormone is decreased or increased there is imbalance in menstruation.
So please do full hormonal profile : Estrogen, progestron, LH, FSH, HCG and thyroid hormone.
That help to diagnose hormonal imbalance.
After confirmation you can take treatment according So please go ahead.
Hope this may help you
All the best.
Stay healthy.
