Trichomoniasis, any STD really, will increase the chances of you getting HIV. It DOES NOT MEAN YOU HAVE HIV.
You can get tested now. Normally you'd show antibodies after about 30 days if you were infected. Usually two tests are given, one now and another at 6 months.
Once you get cured of Trichomoniasis, it can come back ONLY if you are exposed to it again. It is not a virus, it is a parasitic organism.
Hope it helps.
