Hello mam,thanks for trusting health care magic.
It is common to have such pattern at this age but still not to be taken lightly
In case you again get heavy periods
then get an abdominal ultrasound
and hormone assays viz Thyroid function tests
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.
