you need to get worked up again
Detailed Answer:
If you are sure that stool is really dark you need to get worked up again. You may want to check the stools again. If it persists to be dark , you need both upper GI. endoscopy and colonoscopy. Sometimes fissure or hemarroids can bleed but that is XXXXXXX blood but not altered stools.
How long have you been on iron supplement - If iron was taken one week ago, it doesn't cause alteration in stools a week later.
You said you have been taking lots of grape juice. If you been taking grape juice in the past and had no issues with stools, then it may not be related.
It is always better to get investigated since upper GI bleed can cause stool alterations and if neglected will make you anemic.
Take care
