Chlamydia diagnosis and transmission

A week ago i had a surgical abortion..on the day of the procedure a few test were offered to me for free ..one of them was a chlamydia test..i agreed to it..today a week after the termination..i was told that my chlamydia test has come back positive..I have been with my partner for the last 2 years..before him i was in a relationship of 11 years..my current partner told me that he had chlamydia a few years ago but was treated and not tested again or had any checkups following his treatement.. I have had a baby who is 20 months old now.. My concern is..that i do not know how long i have had this for if i got this from my current partner or my previous partner.. a year ago i have had symphtoms which i thought was thrush and i treated this with a thrush cream which helped right away.. Id i got this from my first partner than i could have had it for over 12 years..is this possible..and has it done damage to me..i had a baby boy who is healthy ..could this have affected him and been passed on to me and how would i know if it had..i was 7 weeks pregnant when i had the surgical abortion last week..i got pregnant by having sexual intercourse only one time in that month..so this is telling me that i have no trouble getting pregnant..how can i find out how long ive had this chlamydia for and if i also have PID and damage to my falopian tubes? please help me ..thanks so much.
