Quit vaping at 12 dpo

Hi so I’ve been vaping for the past 4-5 years I did it pretty often I was very addicted. I’m very aware of all the horrible things it does to your body and ofc a pregnancy. I found out I was pregnant around 9-10 dpo and I cut down to just two hits a day until today on 12 dpo when I’m fully quitting because I already feel soooo bad for just these 2 days of vaping after knowing. Did I make it more likely for me to have a chemical? I just had one last cycle so I’m so gonna blame myself if this happens again I feel soooo bad about it I should’ve quit the second I found out. I decided to fully quit 12 dpo but now I wish I did it when I found out I was just wanting my last couple days to lower my usage before giving them all to my fiance to keep away from me. I feel so bad did I do damage?
