It is common to experience heavy bleeding after missed periods, as the uterine lining builds up over time. This is frequently caused by temporary hormonal imbalances. To help control the bleeding, non-hormonal medications like tranexamic acid can reduce blood loss, while NSAIDs like ibuprofen can help decrease both bleeding and cramping. Alternatively, a doctor may prescribe progestins to help regulate your cycle. However, because you missed your period for three months, it is highly recommended to consult a healthcare provider for a proper evaluation and tailored prescription. Please seek immediate medical attention if you feel dizzy, weak, or are soaking through more than one pad per hour.
