I know it's bad PLEASE HELP!!!

Are there any moms out there that smoked before that found out they were pregnant and couldn't stop? Or how did you stop? A lot of people say that they stopped cold turkey but I just seem to not be able too..I feel like I'm already a bad parent. I don't smoke everyday but once a morning to bm I smoke and I really wanna stop..Please help! I'm 5weeks 2 days and I wanna stop like yesterday but the urges keep coming and it makes it worse bc my boyfriend smokes as well PLEASE DONT JUDGE
