Thanks for the query.
Prolonged bleeding after surgery is somewhat uncommon, so better to get evaluated to find out the cause.
Once consult gynecologist, get examined and undergo ultrasound
to observe the endometrial pattern, condition of the remaining ovary.
And with your doctor's advice go for hormonal
profile including estrogen
, FSH, LH and thyroid profile.
With this workup possibly the cause for your problem can be identified and treated.
