smoking medical marijuana

How many  SO or self smoke marijuana and been able to get pregnant?? How long did it take you to get pregnant? Was it a big obstacle to become pregnant after stopping smoking marijuana?? My so uses medical marijuana and we been trying to conceive for 4 years I'm wondering now is that's the issue since I just recently read marijuana is a big factor on fertility 😣 he needs it for severe pain and I don't have it in me to ask him to stop since I know how much he suffers from chronic pain. And he is a hard working person that does need for medical needs. Makes me sad having him suffer and than again not being able to conceive.
