i dont know i havent been as yet but i took a flaxseed oil tablets after dinner so hopefully i will find out tomorow, im not sure what to think if its normal though, i mean the black only showed up in the D and the rest had been normal as normal can be for me before that.i havent contacted the doctor its a bit difficult as im still registered with a doc where i used to live and have just moved away so i dont even know what surgery to go to to register herei was reading about that GI bleeding thing earlier and that got me freaked out though especially since i cant associate it with my diet, i cant think of anything i wouldnt normally eat that i have done
