Hi, I am 33 weeks pregnant. Today I saw a small coin sized blackish substance in my poop. What could it be? Is it due to the iron tablets I took in the night? Do I need to check with my gynaec?

Iron does make the poop darker. If your stools are soft and easy to pass then it is also not due to any abrasion in the bowels. It is always recommended that you report any incidence to the doctor as if there is blood in the bowels it could signify an infection.

I had the same issue while taking iron tablets , still do concern doctor
