It takes one week but you and your boyfriend should not have ANY sexual contact until about one to two weeks AFTER he has been treated so you dont get reinfected.
It takes about a week for it to go away thats why they tell u no sexual contact and if you do use a condom and no you can't get chlamydia by semen only sexual contact The enzymes and acids in your stomach will quickly destroy any viruses and bacteria. Or spit it out, and use a mouthwash to remove any lingering hope this helps
