Abnormal discharge ( sorry :/ )

So, first smear at 28 came back severe changes, colposcopy 2 weeks later didnt go well and had to be cancelled as i was in so much pain, the only thing they managed to do was have a look, remark on the amount of discharge i had (sorry) then take alot of swabs, whem i then spoke to the consultant he said that he was testing me for infections, std's and other things as the discharge was not normal, I just got back from the docotrs appointment and all results came back clear so what could this be??? is it linked to the dyskarysosis? the doc is also recommending i am sedated so that they can finish the colposcopy and do the LOOP. Any advice greatly recieved.
