Missing periods for two months at 19, with no other symptoms, is usually linked to stress, a change in weight or exercise, or an underlying hormonal pattern such as PCOS or a
thyroid imbalance. These are the most common reasons in someone your age, rather than anything more serious.
Next Steps
A
thyroid test (
TSH) and a hormone panel (
LH,
FSH,
prolactin) along with a pelvic ultrasound will usually show the cause. Please see a gynaecologist to get these done and discuss the results.
Health Tips
If you also notice sudden weight change, excess hair growth, or periods stay absent beyond three months, mention this to your doctor too.
