Mild stomach discomfort. 2 days yet.

I was having mild discomfort in stomach from a week so took ct but had some issues so again went for endoscopy but during endoscopy power went off and scope was there in mouth for 10 mns then again second time done when power came due to rich or something doctor told mild bleeding so gave medications and stopped it and after sometime third time endoscopy done to check bleeding stopped so doctor told it stopped so my question is ,is it ok to do endoscopy simultaneously 3 times in 3 hours durations .just a feel nervous and on medications as of now for ibs .have attached the reports .h pylori negetive .is it anything to be worried about as doctor told bleeding stopped but yet some nervousness and when will the bloating stop as it's been 2 days yet.
