Hello mam, thanks for trusting health care magic.
It is common to have heavy bleeding after prolonged duration so just wait for another cycle and see for the flow.
in case this psttern persists or you again miss your periods then get an abdominal ultrasound
and hormone assays viz Thyroid function tests
levels to see for the cause of this altered pattern of periods
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
