Thanks for the query.
Better to consult gynecologist once.Hormonal
imbalance may be the cause for your bleeding.
As you stopped the pills in the middle, that withdrawal might have added to the bleeding.
So you consult gynecologist, get examined and take tablets to stop the bleeding.
Go for one ultrasound
and if your doctor recommends you can go for hormonal profile including estrogen
, FSH and LH, thyroid profile etc.
With this workup the possible cause for your problem can be identified and treated.
