Regular pot smoker prior to pregnancy


So I have smoked pot for 10 years regularly. I found out I was pregnant and have completely stopped. Now I know it takes awhile to get out of your system if your a long time smoker. How does this affect the baby? Should I tell my doctor at my first appointment? I'm 6 weeks and have not smoked since the day I found out which was 2 weeks ago. I do NOT plan on smoking at all throughout this pregnancy or after baby comes. Please don't judge me.
