unusual "period"/discharge

There is no particular pleasant way to describe this, but 11 days now since I started my period I am not bleeding, but am having some unusual pale tissue-like discharge on and off now for few days. This only seems to be coming out when I go to the bathroom... Not sure if this is related to either, but has anyone experienced similar after a colposcopy / biopsy? These were taken nearly 4 weeks ago (I have a history of irregular periods, PCOS and a mirena coil that seems to no longer be stopping my periods since all this cervical abnormalities started). 



Also my post-colposcopy gungey discharge stopped after few days
