No, you should not start Sysron-N on your own if bleeding has not stopped after Trenexa. Continuing or switching medicines needs a gynecologist advice, because persistent bleeding can have underlying causes that need proper evaluation and treatment.

If you have irregular periods and daily bleeding after taking Sysron-N, stop self-medicating and see your gynecologist. You may need a dose adjustment, a different medicine, or tests to check hormone levels or rule out other causes.

For heavy periods with clots and weakness in a 15-year-old, ensure she gets enough iron through diet or supplements and stays hydrated. A gynaecologist might check for hormonal imbalance or anaemia and may prescribe medicines to reduce bleeding.

Sudden heavy menstrual bleeding can happen due to hormonal imbalance, stress, thyroid problems, clotting issues, or infections. Sometimes, uterine growths like fibroids or polyps can also cause it. It is important to see a gynaecologist to find the exact cause and get proper treatment.

To reduce heavy bleeding and weakness during periods, take iron supplements if recommended, eat iron-rich foods (spinach, dal, eggs), and stay hydrated. Avoid strenuous activity, rest well, and track your periods. Your doctor may also prescribe medicines like Tranexamic acid to reduce bleeding safely.
