Lung tb 10 years ago, miscarriage at 13th week last year, is it possible caused by the tb in genital system that was infected by lung tb?

Unlikely: Lung TB usually confined within lung and nothing to do with miscarriage . Genital TB very rare and unrelated to lung TB in most of the cases except milliary tuberculosis ( special condition of disseminated tb). Further more, miscarriage has many common cause, so unlikely lung TB 10 years back caused the miscarriage . Consult a gynecologist
