hi! may i tell you first the story, my husband slept with some girl somewhere without me knowing about it. then the night after he slept with me. 2 to 3 days after, i have observed that i have yellowish discharges. though these discharges don't smell like fish, they do itch specially when i don't change my underwear after 8 hours. when we were having sex, it is painful at the left portion of my abdomen. what medicine should i take? since at present i am taking co-amoxiclav as an immediate treatment.
