I had chamydia (now cure) 2 months ago, a week after treatment i felt a little itchy, the gynecologist did a vaginal swab test and the results were normal, however i've been experiencing stretchy yellowish discharge and a mild itch, what could it be?

Get rechecked: Itchiness suggests a yeast infection, which can result from antibiotics used to treat chlamydia or other infections. But yeast usually doesn't cause much discharge, and not "stretchy". Maybe reinfected with chlamydia: up to 20% of people with chlamydia have it again in a few weeks, either because treatment wasn't comletely successful or from reinfection. Return to your doctor or clinic. Good luck
