Hello. I'm 35 Weeks Pregnant And Quit 2 Days Ago.

Hello. I'm 35 weeks pregnant and quit 2 days ago. My morning sickness has been God awful and I've lost a ton of weight so I kept smoking to eat. How can I get this out of my system so they don't take my daughter and son from me? I'm a good mother I do everything for children and would never put them in harms way. So please no bashing on me for smoking. Had I not I probably would have miscarried. Please help me
