Hi! Yes!!! I have had maybe 10 major upper GI bleeds over the past 7ish years. They tend to be quick and by the time they get me in to have an endoscopy, my stomach may be a little bloody but they are unable to find the source of the bleeding. I am not sure how frequently your daughter has these issues, but mine happen infrequently enough (knock on wood haha) that it appears to be a slight inconvenience in my life. The last time I had a GI bleed, my doctors got me in within ~5 hours and found an area they thought might be the location of the bleed and added clips to it. I am hoping to have another endoscopy soon to see if inflammation in that area decreased. I hope your daughter feels better!
