You are suffering from Polymenorrhea, where in the cycle last for less than 21 days. This could happen due to, Hormonal Imbalance, Pelvic Inflammatory Disease
, Fibroids, PCOS, stress, change in diet or exercise routine, recent weight loss
or weight gain, travelling or illness. You should be getting yourself examined by a Gynecologist and if possible get a Ultrasound scan done to rule out the exact cause. If necessary, your Doctor may also suggest Hysteroscopy
to evaluate you further to rule out the exact cause.
Avoid stress and eat healthy nutritious balanced diet which should include fresh fruits and green leafy vegetables. Kindly do not delay and see your Doctor at the earliest.
Wish you Good Health, Take Care.
