Missed period for 2.5 months is not normal. There are several reasons of missed period like ovarian cyst
or PCOS, hormonal imbalance, mental stress or depression, taking psychiatric medication, over weight, pelvic infection
, anemia, improper diet habit etc.
Here, I suggest you to undergo some investigations like pelvic ultrasound
scan, hormone test (thyroid, LH/ FSH, testosterone
), blood Hb% & sugar level etc. These will help to make a diagnosis and give proper treatment. You can consult with your gynecologist for proper guidance.
You need to control or reduce body wt by regular physical exercise, avoid mental stress, take low carbohydrate
diet and hormonal medication.
Hope,it helps for you. Good luck.
