Ive been happily married for 3 years and I havent been able to conceive.My husband has 3 children of his own , so I know hes not the one with the problem. Im not a smoker but my husband is, and Ive heard that smoking has somthing to do with the male sperm causing women not to get pregnant.(dont know if its a fact though) I was also wondering if maybe its cause my hormones are unbalanced. How would I know if they are? I know Im not the only one with this proplem but conceiving is my concern.
