day 18... my bm is still "regular" brownish? :o

just been reading about how everyone's getting yellowish-orangey bm... at this stage i have no actual solids coming out to speak of, but the color is still regular brownish...? is it because my liver is still producing bile...? (i heard that liver bile is responsible for the brown/greenish bm color... ) and if my liver is still producing bile, am i not successfully giving my digestive system a rest...?!! a bit confused here... :-\
also i get bm VERY REGULAR... more than 3 times a day, which is good... some days i hardly have to take swf, cos i just start the spontaneous evacuation in the morning.... Tweet
