Hello, and I hope I can help you today. The black color to your stool is a likely side effect of the iron in the Orofer you are taking. It is normal for the stool to look black from iron supplements. If the tablets are also making you very constipated, it can sometimes cause blood to appear in your stool. However to make sure you are not really bleeding from your intestines, I suggest you stop the Orofer and try a tablet instead that has only folic acid. You should be on folic acid if you are trying to conceive again, but the iron is just a precaution unless you normally are anemic. If you still see black and bloody stool after not taking any iron for a week, you should see a regular medical doctor because you need to be evaluated to see why you are bleeding. None of this has any bearing on your ability to get pregnant again, you just may be sick or having a side effect from the iron in your tablets. I hope I was able to answer your question and that this information was reassuring. Best wishes, Dr. Brown
