There is no single medication for irregular periods, as treatment depends entirely on the underlying cause. Irregularity can be triggered by stress, thyroid issues, hormonal imbalances like PCOS, or sudden weight changes. Self-medicating with hormonal pills without a proper diagnosis can be harmful and worsen your symptoms. I highly recommend consulting a gynaecologist. They will likely advise a pelvic ultrasound and blood tests to check your hormone levels. Once the exact cause is identified, they can prescribe the safe and appropriate medication tailored to your body.
