If i had chlamydia twice not sure how long but not treated does that mean i won't be able to have kids ?

Maybe,maybe not: You may have had little effect or lots.Early treatment always improves your ability to reduce damage.The germ can travel up into your fallopian tubes and cause inflammation & scaring that might prevent a natural pregnancy or place you at risk of a tubal pregnancy in the future. Time will tell. Discuss it with your obgyn for specific risks based on your own exam.
