Medical marijuana for severe morning sickness

I was just wondering what everyone's thoughts are on medical marijuana for all day severe nausea and vomitting? Anecdotally I believe it is better for you and baby than most prescription drugs they will give you and is essentially just a herb. I had some last night and today is the first day in two months I have not been sick or nauseous and able to keep food down. I am 9 weeks, would not continue past 13 due to brain development but I'm just curious what others think?
