Irregular periods (2 times/month) can happen due to hormonal imbalance.
A
TSH of 0.63 is within the normal range, but if it is on the lower side for you, mild
thyroid overactivity can sometimes cause frequent bleeding.
Other common causes include stress, recent weight changes, PCOS, ovulation issues, or uterine problems (like fibroids or infection).
Next steps:
Consult a gynecologist and get tests like T3, T4, pelvic ultrasound, and hormonal profile.
If bleeding is heavy, prolonged, or associated with pain, see a doctor soon.
