How long before chlamydia causes pid?

Uncertain: If untreated, 10 to 15 of women w chlamydia may develop pelvic inflammatory disease (pid). Pid may start developing within weeks to months of infection.

Chlamadia: About 50 % of chlamadia infection is asymptomatic and so it is hard to say when someone got the infection. However if treated on time along with gonorrhea may not get pid, but if lower abdominal pain sets in, pain during coitus or pain during or after menstruation in pt with chlamadia, suggest pid and should be treated immediately.
