Yellowish greenis discharge after being treated for chlamydia and trichomoniasis. i feel odd inside but no burning or itching. yeast infection?

Yeast infec unlikely: Yeast infection is not uncommon after antibiotic treatment, but usually is associated with itching and a white cheesey discharge. Yellow green sounds more like persistent infection with trich or other bacterial vaginitis. I recommend that you be reexamined and retested, to include GC and BV as well.

Yeast: is not yellow/ green. It is usually white and clumpy with no significant bad odor.
