HI,It is not clear by your complaint what colour stool you are passing. However if the stools are dark coloured, this could be due to certain food you might be eating. Like dark green leafy vegetables. or beetroot etc. Some Iron tablets also alter stool colour. If the stool colour is light, then you should get your serum bilirubin
tested. Sometimes in pregnancy liver
is pressed so bilirubin increases. It becomes all right after delivery. Take care.
