Thanks for your question.
Iron preparations take about 4 days to start showing their effects and side effects can also last for many days after stopping.
The effects staying so long is normal and you need to give some more time for side effects to go away.
Still if stomach pains are severe and persist it would be safer to have a doctor look at you to rule out any other cause causing the abdominal pain.
I am a different expert. It is not normal for diarrhea, loose stools, to persist a week after stopping iron pills.
I would strongly recommend that you should be evaluated further and have a stool test to rule out an infection.

You can book an appointment with the GP.
I am sorry for the late response as I was away all day today.
