Need help

Kristie

Me and my wife as been trying for two years. I help her take care of her cycles because she is a stay at home mother with her first born. But I do claim him as my own because the father was a druggy. So I’m the only dad he knows. The thing is I need help to figure out what I can do to help make a baby with her we tried everything. I’m starting to think it’s me I don’t know what to do. Someone please help.
