Thanks for the query.
The possible causes for your bleeding are :
- After stopping the contraceptive pills
, it will take some time for regularization of the hormonal
And this can lead to irregular bleeding.
- As you didn't use contraceptive measures after stopping the pills, there is possibility of pregnancy
-Other causes of heavy bleeding are thyroid
hormonal abnormalities, structural causes like polyps, fibroids etc.

So, as the bleeding is persisting, better to consult gynecologist once and get evaluated.
By examination and ultrasound, one conclusion can be drawn regarding the cause for your problem.
And treatment can be taken accordingly.
