long period after stopping bc. wait it out?

Hi
Welcome to ehealthforum,
It is difficult to comment on the exact cause for the prolonged menstrual bleeding/periods that you describe without examining you and going ahead with further evaluation. Prolonged menstrual bleeding/period is not normal and should not be ignored. Further evaluation must be done to rule out chances of hormonal imbalances, thyroid abnormalities, anemia, bleeding disorder, vitamin deficiencies, probable ongoing miscarriage/incomplete abortion (if your fertility has returned, and if you have been sexually active), endometrial hyperplasia/changes, etc. You should consider visiting your doctor/gynecologist at the earliest for examination and further evaluation to look for the underlying cause. Treatment as indicated (based on examination findings 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 care.
