Being under government medical care my concern is they would brush you off to keep from spending more money on a person..I hope I'm wrong as it looks like the US may someday head that way.
As far as the discharge goes..my girlfriend that had given birht a few months earlier had a discharge like that also. She had what is called a blocked milk duct. She manually squeezed it daily and eventually it was oK.
On the other hand I have heard of OLDER women that had a discharge that had blood in it and it was cancer.
So either way I would also encourage keeping an eye on it. I would say it is related to her nursing and possibly a stopped up milk gland. Good she had it checked out.
