In the setting of abnormal bleeding that is not being easily controlled with hormonal therapy, it is appropriate to undergo a more thorough evaluation that would include:1.  An exam2.  An ultrasound3.  Labs that would include testing for thyroid disease, diabetes and prolactin levels4.  A pregnancy test! I hope that this helps.
