Help me please!!! GYNO problem for a year!!!!?

I am 25 and I have had gyno problems for over a year now. I have normal pap's but an abnormal cervix... Every time I go all of my tests come back normal. All std's and even my pap's. My gyno can see there is a problem with my cervix and doesn't understand why my test's are showing as normal. I have a strange discharge that has no smell but it is unchanging and there all of the time. It is on my underwear and I can push it out of me every time I use the bathroom, it doesn't have a smell and according to the guy I was dating it tastes great. Anyone have any ideas? Since this started my periods have also been very light, only about 2 days long and hardly any blood.
