I feel so guilty...

I’m 26 weeks Pregnant and I smoked before the baby. I finally stopped and didn’t smoke at all while pregnant except for a few hits off a Juul here & there. I smell cigs and crave them. I crave nicotine. I crave the Juul but I know not to smoke them a lot since I’m pregnant. Today I gave in to the temptation and split a Camel crush with a friend. Will that one hurt the baby?? I’m so scared and so worried that I did do something so awful. 😩
