Re: PP 6 months breastfeeding and still bleeding
Definitely time to seek a second opinion. Like LLLMeg, I have never heard that breastfeeding was associated with bleeding such as you describe- quite the opposite, in fact.
If the ultrasound was clear, meaning that there's no physical explanation for the bleeding, the cause could be hormonal. You might want to see an endocrinologist in addition to seeing a gynecologist.
This is a good article on abnormal uterine bleeding: http://www.aafp.org/afp/2012/0101/p35.html
