It is sometimes possible that the iron tablets you are having can themselves cause black stools. However if you have black colored blood in your stools then it is a different thing.

The unawareness of bowel evacuation does occur sometimes and is not of any concern.

It is also normal to have back pain during this stage of preganancy due to the weight of the uterus.

If your referring to your pregnant uterus as being hard, then that too is normal due to the fluid present in your uterus. If however, you develop any pain or vaginal discharge then it is important to consult your obstetrician.

Hi,
Welcome to HCM,
Black stool might cause due to iron supplement you take for anemia.
Due to iron you might got constipation even you pass loose stool, might giving pain.
But as you are having full term pregnancy and having low back pain might be an indication of labor pain.
If pain and tightness in stomach persist, consult your obst and get examined.
Take rest.
Ok and bye.

Hi friend,
Welcome to Health Care Magic

Black stool is most likely from iron supplement.
However, it can also be from gastro-intestinal bleeding - have your haemoglobin checked.

Take care
Wishing speedy recovery
God bless
Good luck
