we know that untreated chlamydia can lead to many problems including pid and scarring of the fallopian tubes (this can cause a tubal pregnancy) but it would not be possible to determine your "chances" of this happening. i would strongly suggest that any future partner(s) use condoms 100% of the time and that you be routinely tested for chlamydia and other stds that may have accompanied this sexually-transmitted disease.
if i have had chlamydia untreated for a yr what is the chance i will have pid or other problems? i have had 0 symptoms.
