Okay I been smoking since March, so itll be easy for me to stop doing it,,, buttt I just found out I’m pregnant with my second child (could be around two mo) . Is there any healthy ways & safe things I can do to help clear my system while being pregnant?

I know there’s a good chance that if I set up an appointment with an OB they will pick something up, because it’s not only in my system but obviously whatever I intake so does the baby. I would rather have less of it in my system so any ideas will help. (Sorry if this is dumb. I never really smoked before & I have been non stop since March. I don’t really ask a lot of questions.)
