Uterine bleeding?: It will be important to first determine the source of your bleeding; gynecologic or non gynecologic. The causes of genital tract bleeding post partum abound, the role your thyroid function plays in the complaint should also be considered. Please seek out a consultation with one of our reproductive endocrinologist for proper evaluation. Wishing you very well.
