My wife is not been pregnant for the past 5 years

five years with our marriage my wife did't have a pregnancy

Well did you have sex? If not, then this is normal...

Is she taking the pill or preventing a pregnancy for a reason you may not know about?? Maybe she wants a career or more stable home life first and doesn't want you to worry. OR maybe there is a medical problem that should be checked in to first. She needs to see a doctor to make sure everything is ok - and you both need to have a serious talk!

Enriqua is right there might be a medical problem, and you need to look into that. But remember you can always go to an adoption agency or keep trying to look for some ways to still have kids. :D
