Hey Veronica, the blood loss sounds normal to me too - I was wearing liners for weeks and weeks. Towards the end the blood stopped, but there was yucky discharge for a while after that.
In regard to the pain when you pee, I'd talk to your doc. It may be nothing. But its so easy to ask, and if its something that needs looking at you'll be better off looking at it, KWIM?
I remember I thought I had thrush at one point, cause while the stitches were healing they were a little bit stingy and itchy... But the doc checked them out and said all was fine - just healing. Maybe when you stop the wee-flow, some gets on the stitches/scar or something? I found using a little spray bottle of water when I went to the loo helped them not to sting - diluted the wee Also, drinking lots of water made it more comfy too. HTH and hope you're feeling better soon.
