Vaping while pregnant?

So I just found out I was pregnant & I’m 23 weeks. I’ve always had irregular periods and I’ve even had what I thought was my period a couple of times. But I’ve been vaping so my question is if I stop now will it benefit the baby or is the damage already done?😭. I stopped the moment I found out but I’m so worried I’ve caused something bad to happen to the baby.. please help?
