Hi,
I assume that your menstruation started recently. In the beginning, the cycles are very irregular and may
result in prolonged and heavy bleeding in some girls and absent periods in others. It may take over a year for
the cycles to become regular. Bleeding is usually scanty and brown at the end of the cycle. A gynecologist
examination is necessary to check whether the symptoms are usual Menarche symptoms or whether there is a
disorder that could be causing the heavy and prolonged bleeding. Hope this helps you. Take care and regards!
