I think I agree with Wazza @infinity888 colonoscopy would be your best bet.
I have heard of ladies getting constipated when they stim and pear juice can help but not the bleeding and the pain. That is not wazza related either just linked to stimming med in general I think.
It's good that the bleeding has stopped but a check up still wouldn't hurt. My mum get a colonoscopy done every year she gets pockets in her bowel that cause a lot of discomfort it has a huge medical name plus I also know pain and discomfort can come from IBS which is linked to stress so there are quite a lot of common bowel issues out there. Hey good luck tomorrow try not to stress too much just one day at a time okay xoxo
