Hello,
Hormonal imbalance is one of the
causes of
irregular periods as well as infertility. The cause of
irregular periods could be due to hormonal imbalance, stress, chronic illness, polycystic ovarian disease, thyroid gland disorders or diseases, pituitary gland tumors or cyst, galactorrhea, prolactinomas etc. You should consult a gynecologist and get examined and investigated as soon as possible if you are having irregular periods.
I hope it helps.
