Abnormal periods are common in early age of menstruation
Apart from that menstruation depends on weight, other hormones including thyroid
, PCOD,ie poly cystic ovarian disease
Thyroid related disorders are common in females and at times run in family. So get a thyroid profile done and counsult a gynecologist and if required an endocrinologist
At present I am not able to assess the severity of the disease so cant say what treatment is required.
Dont get tensed or panic. Take care.
