Thanks for your question. It seems your question is not complete with details. Fertility depends on the kind of leukemia you had and the type of treatment you got. Usually, drugs used to treat leukemia can affect fertility. For you, still there is a chance of getting a 40-50% difficulty while conceiving and after that. It is also affected on the dose of treatment, duration of treatment and regimen used for it. You better ask your doctor to know which type of regimen was used. Have a thorough medical checkup before getting pregnant. It can help in avoiding further complications at the time of delivery or so. Good luck.
