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!
