Smoked while pregnant.

I'm almost 12 weeks pregnant and I smoked marijuana everyday of my pregnancy. I truly regret my decision I honestly just thought it wouldn't be harmful to the baby and I didn't know I was pregnant til 8 weeks and quitting was extremely hard. I've had a huge change of heart and I've stopped smoking and will never do it again while I'm pregnant. Do you think I have anything to worry about for the baby's health? I have awful anxiety about this and feel like a terrible mother. I feel sick to my stomach every time I think about it. Please share your thoughts
