Is my husband the reason I can’t get pregnant?

Dominique

So I’m 22 years old and me and my husband of just a year have been trying to get pregnant for almost three, we have very good jobs and we’re stable so we thought it was good, but my husband is a very big pot smoker, he doesn’t even go a day without smoking and I heard that the constant use of marijuana can be a reason I’m not able to conceive, We really want a baby but it seems like he doesn’t believe me when I tell him it’s probably the pot making it so I can’t.
