I want to know I if can get pregnant its been like 5 yrs using no condom or no birth control nothing and I haven't ended up pregnant and I want to know why??

Only a doctor can give you a proper answer to that, maybe you could be incredibly unlucky, Have you been using an ovulation kit to monitor your " fertile window". Do you have any medical conditions, concerning any part of the body that could effect pregnancy, does you husband have a low sperm count, these are only a few of the many factors, the only way to get a real answer would be to talk to a doctor.
