Weed while pregnant

I'm just curious who smoked or used cannabis while pregnant. I am really just trying to see what you experienced and if you used it to help with pain or the morning sickness. The studies that are out there are skewed because they aren't controlled studies and the moms were using other things like alcohol and heroin and meth. But the few that didn't use anything but weed their child was 100% fine but there weren't enough using only weed to make the studies classify it. 
My morning sickness is so bad I lost 30lbs in a month because I cannot keep anything down, I have chronic kidney stones and infections and I'm in so much pain constantly from it, I used cannabis to help with that before finding out. 
Please be honest with me and please no one bash anyone giving helpful answers for their choice. I just want help. And I don't want hate on this.
