What do you think will happen between now and the 7th that would change things? Do you want your scope earlier? Do you want different meds now to reduce the bleeding? Are you using rectal meds?
Are you asking this because you're afraid you might bleed too much to live? I wouldn't worry about that. You might still be anemic even if you're taking an iron supplement, but you're not bleeding enough to go to the ER, IMO.
