Hey, has your Husband gone to a different doctor or just go to a doctor that knows a little something about vasectomy and have a doctor take a second look to make sure the procedure was done right. My mom had already had four girls (which two were a set of twins) and told my dad to go get what I like to call his man hood chopped off!
So he went and was cleared from the doctors but my parents still waited a year or so to even have sex and when they finally did BOOM and thats how my little brother happened.
It turned out that the doctor was STUPIED and had actually messed up on MANY others (HAHA and was in the process of being suied I do believe) and my dad had to have the procedure done a second time, though he wasn't happy AT ALL about it, but that time it was done right. (this is sad) but if i have my moms age right my mom was about 30 or so when she had my little brother, and my brother came out fine and my mom had a good pregnancy.
