Does marijuana affect the chances of a BFP??

Shaina
I've been hearing this myth about marijuana affecting fertility in humans, but I've also seen so many women who indulge recreationally and have more than one child!! I'm very confused on the matter! My hubby and I are TTC for baby #1, we are very healthy, my cycle is very predictable since I was 10, and we just did the BD for my entire fertile week! Are my chances slim to none if I have indulged recreationally too??
