its not a lot and maybe tmi! but often when i wipe after using the loo, there is old brown blood, not a lot and no odur etc just obviously its not right.
there is no way i could be pregnant as dh has had a vasectomy and the all clear, as was over a year ago now.
This period was a bit clottier than usual but have never had this after, normally my period lasts for 5 days and that's it until the next one.
I googled and now know i shouldn't as according to google either i have cervical cancer or my h has cheated on me and given me something nasty! 
i don't really think it is either one of those tbh, am guessing the advice will be go to your GP?
