hello ladies! quick question?!

I am a former smoker of 8 years. and once i found out i was pregnant, i immediately, cold turkey stopped smoking. I am 5 weeks 2 days and haven't smoked since i got my BFP. I am very much struggling, and craving nicotine. I refuse to smoke but it is hard and i am tired of the urge. I have been wanting to stop and now I have a good reason, i do not plan on smoking after either so my question is if you smoked previously to getting your BFP what helped you fight the urge to not crave nicotine? I want my baby and myself healthy as can be so please please comment and let me know what helped you. Chewing ice is not cutting it for me 😕 please don't judge me, i smoked for a very long time and haven't ever since I got my BFP. Just want to know how to stop the urge.
