When to quit

Ladies! Me and my hubby are finally preparing to try and conceive our first child! While I’m excited, I’m also nervous. I’m starting to take pre-natal vitamins and eating better, but I have a question. Both of us smoke weed, usually share a joint right before bed. How long should we quit before we actually try to conceive? I did my research and there’s too many up in the air research about if it’s okay so I ͏want to be 100% safe and just quit it completely. So again, how long should I go without smoking before I attempt at making our baby?! Also, if you know anything about weed & pregnancy let me know ❤️
