If your treatment was successful then you should be able to get pregnant. You can try having your partner to get evaluates and tested to see if that is the problem. You can also make more inquiries with your doctor.
Depends if it was treated or not and how long you had it. However there are loads of reasons why you may not become pregnant and it may be to do with your body or your partner's body so it is best for you both to visit a doctor :-)
