Orange, creamy dischare

So I have been having some odd-smelling, heavy discharge for couple of months now (used to be slightly yellow, with consistency of a cream) Been tested for chlamydia, hiv and bv but all came out negative every time. Today it was orange.. I am seeing a doctor in 3 weeks earliest unfortunately. I am suspecting trichomoniasis since I dont experience any itchiness or burning but shouldnt that have come up with all the other tests? Any other ideas? Done pregnancy test as well but its negative.
