(TMI) I don't have insurance but I could use some advise

I am usually very private but I don't have insurance right now. I'm finding myself desperate for answers but can't afford to go to a doctor right now so I try to look things up online. 
So I guess I'm hoping if I share what I'm dealing with someone may shed some light or maybe knowledge on my situation. 
I from time to time, have this weird clumpy discharge. It comes and goes. It sometimes has a yellow green color to it. It has no smell. I don't itch I'm not experiencing any pain whatsoever. It just comes and goes and I don't know what to make of it. I'm embarrassed to even post this
