Pregnancy safe ways to stop smoking addiction?

Tamara • 20 & engaged :) wasn't planning on this, but we are so excited none the less! ❤️😍👶👪
I know people who smoked throughout their entire pregnancy and we're fine, my mom did with me and all my five siblings too. But I want to stop! I'm having a hard time with being able to simply go to the store and buy more should I eat one, are their any kinds of gums or patches I could safely take while pregnant? What helped you? I'm 12w 3d. Please no judgement. I know it shoul be easy to stop because it's bad for the baby, but it's so hard. I'm 20 and have been smoking since 13.
