Hi .... i know i might get disapproval for this but it is a serious question . I am a smoker .... i am 4 weeks late on my period and whenever i smoke i get incredibly dizzy and nauseous, i also have decent amount of back pain and bloating to the point where i can hardly fit in my jeans .... Is nicotine rush a sign of pregnancy ? Im terrified to take a test because of my miscarriage two years ago and i cannot go through it again. I know if im pregnant i need to find out so i can make lifestyle changes.... Any advice or knowledge would be greatly appreciated
