I am 28 year old woman and a mother of 3 year old kid. I am having irregular periods from my puberty onward. I am maintaining a healthy bmi, my height is 154cm, nd weight 49-50kg. I dont have pimples or facial hair. Bt my hair started falling heavily after delivery, dat too from the front portion of the head. Quarterly only i'm having periods, and flow and duration are normal. I dont have any significant difficulty or health issues except dis long gaps. What should I do?
