hello,
I've had that type of blood too...

I was told by my natural fertility specalist that brown blood at the begining of a period is old blood, and that the blood is not moving through my body quick enough? Has to do with the liver? So all types of liver cleansing tonics / herbs work for this type of blood stagnation.. Anyway, this is what she told me, so I hope this helps you?

If you want to try some home remedies, maybe try a liver cleans, and maybe fresh juice like carrot, beetroot and celery with ginger and parsely and increase your water intake to help your liver... (I'm sure it can't hurt anyway)...
I hope this helps....
