Smoking weed while pregnant

I know someone who's been smoking weed even before she was pregnant .. When she found out she was pregnant she stopped , her whole first month was non stop morning sickness , couldn't keep anything down , not even a sip of water , couldn't eat anything without throwing it up .. It went on for about a month , she was laying down , depressed , sleeping all night all the way till 5 in the afternoon , barley hungry because she knew she was going to throw up . One day her aunt came over and told her to hit a bowl and that would make her want to eat , "munchies" I guess . She did hit the bowl , she ate afterwards , she was actually hungry and could actually keep it down , she started gaining weight within time , eating right , no as much morning sickness , Hardly any now ... I want to know if this has happened to anybody .. Maybe your scared to opening admit you smoke weed ... Scared as in what people are gonna think of you ... I would like to hear some of you ladies stories ..
