Does weed affect fertility?

Me

Hey y’all my boyfriend asked me the other day why it is that we haven’t gotten pregnant and mentions it every now and then. We don’t see each other everyday so I know that’s one reason why, I also just now started taking ovulation tests, and he smokes a lot of weed. We aren’t really trying but we also aren’t doing anything to prevent something from happening. I was wondering if the fact that he smokes weed everyday has anything to do with it. Also I’m 21 and he’s 26 and we’re both fairly healthy.
