Hello new mamas ,

I have just recently found out that we are expecting. This is my first baby, and I’m about 5 weeks and 3 days. Please no judgment on this as this pregnancy was 100% not planned but we are extremely excited anyways. I am a smoker, I smoke cigarettes, I have cut back a lot since i first found out that I was expecting. Is there any advise on how to quit indefinitely? I have heard that quitting sometimes is worse off because it puts stress on your body. Please let me know your thoughts! Thank you!
