smoking weed while pregnant

I'm really curious what mom's have smoked weed while being pregnant? Was your baby healthy, did you have any problems, did it help with the pregnancy? I just want to be more informed on this topic 
UPDATE** 
I never said anything about me smoking weed? I just wanted to be edcuated on the topic and not ignorant about it. But thank you to everyone who commented, much apperiatcted 😌
