Smoking While Pregnant

Well I'm 7 weeks 3 days pregnant. Before I found out I was pregnant I smoked weed heavy and then I calmed down and now I've stopped. But I've been soooo nauseous and not able to eat and weed is the only thing that brings my appetite instantly.  I only smoke papers and don't even really like smoking while  pregnant but it's the only thing that gives me and appetite and calms my nerves😖
