When I found out I was preggo with my second I smoked we*d and cigs. The day I took my pregnancy test and it came out positive I completley quit both. I have not smoked either one in almost 2 yrs. My baby girl came out perfectly healthy and almost 10lbs...lol prolly from all of the eating I was doin because I was quitting...lol. I will admit it was very hard to quit especially both at the same time, but I just tried to keep myself occupipied with other things so tht I wouldnt think about it, I just felt sorry for my poor husband because I was a Bi*CH...lol
With that, no because there are no chemicals that the baby could get shocked from if it went away. But I would slow down on smoking to keep yourself sane and not stressed because I know when I quit smoking weed my depression came back hard, along with insomnia, anxiety, and a lack of appetite. I lost 20 lbs in a week. This was before pregnancy though. Just ween yourself
