I’m 21F (nearly 22) and had blood in my stool on 2 occasions about 2 and a half years ago. Then 6 months ago I saw blood in my stool again, went to GP, had a fit test and blood test done. Fit test was negative. A couple months ago I saw a bit of blood again, but it wasn’t lots and since I’d just had a fit test I decided to not doing anything, but just keep monitoring. Then, for a separate reason (no period for 6 months) I had another blood test. I’m feeling concerned as my iron had dropped from 53 ug/L in my first blood test to 20 ug/L in the one I had last week. What if this is related to the blood I was seeing in my stool? Should I contact my GP again? I’m so anxious
