What is this discharge?

Ive been checked for stis. It came. Back negative but I have this profuse thick constant discharge daily, its yellow/grey and mucusy, it smells odd, not fishy at all but strange.

Everytime i wipe i have I have it, i took a photo. Is it cervicitis?

I have a similar problem been checked for infections all clear,for 3 months now I've had tiny bits of green discharge pretty much everyday,no smell it's just there when I wipe,starting to scare me now.

This should help you add images:

If you're using a phone or tablet, you may need to choose the desktop/PC option in your browser, or if that doesn't work, you may need to use a PC or laptop.

Did the people who tested for STIs not have any suggestions though?
