Great job!: Congratulations on your decision to quit smoking! Your body will thank you and your baby will thank you!

Quit smoking: Congratulations. That is great news and hope you stick to it. Your question was not clear, but this will have a good effect on your pregnancy and also on yourself. Keep this up and pat yourself on the back for stopping. Best wishes.
