Hello, Welcome to HCM, I am Dr. Das
Look, your symptoms are quite suggestive of polycystic ovarian syndrome
What you have to do are
1. Do an ultrasound
scan of whole abdomen to find out any abnormality.
2. Do a hormonal study comprising of estrogen, progesterone
, LH, FSH, etc.
3. DO a thyroid profile test to rule out any possibility of hypothyroidism
Lastly, consult with a gynecologist for the above mentioned points.
