back on BC, on period for a month

Hi,
Welcome to ehealthforum,
Sometimes you can have irregular bleeding or persistent bleeding when you get re-started on hormonal birth control. Prolonged bleeding that you describe is not normal. You should consider visiting your doctor/gynecologist for further evaluation to look for causes like hormonal imbalances, thyroid abnormalities, endometrial problems, uterine polyps/fibroid, anemia, bleeding disorders etc. You should consider reporting to your symptoms to your treating doctor/gynecologist for further evaluation to look for the underlying cause for the abnormal and prolonged vaginal bleeding that you describe. You can also consider taking second opinion from another gynecologist (if required). Further treatment measures as appropriate (based on examination and investigations results) would be started to help you control the bleeding and regulate your periods. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet.
Take care.
