Julie,
You are not a weirdo... trust me
It could be that you never noticed the mucus before. I had IBS many years before I was "brave" enough to inspect my BM or the toilet paper so who knows what I missed. The hemmies are inflammed and inflammation can create pus which is like mucus so its all very normal. Did she give you some suppositories or something for the hemmies to heal? With the mucus and possible treatment, it might be a good idea to wear something like a panty liner towards the back so you can continually freshen up by cleaning yourself up and changing them out when you go to the bathroom, aloe baby wipes are good in addition.
And don't be worried about
being "gross" here... we are all used to it and we live with it everyday... besides where else can you go to talk about
this stuff :)
Take Care
