Welcome to the gastroenterology community! I think that the answer to this depends. First, if it has only happened 3 times in 8 months then that is really uncommon of an occurrence. Second, it depends on the amount of blood that comes out each of these times. Third, it depends on what other tests have been done.
The dr did find h. pylori in one of the test. I was treated with 2 weeks of 2 antibotics and pepto. I've had a FOB done that was negative. I also blood work done that was all normal. The dr also did a digital rectal exam and found nothing abnormal. I think i'm just being a wimp! But sometime the mind just gets going!!
I don't think you're being a wimp, it is normal to be worried. Although this is just my opinion, and it is always best to get tests done ASAP, if you are only having bleeding occasionally (assuming the bleeding is only small amounts) then 9 weeks won't cause any damage to you.
