Smoking and pregnant

While I was pregnant I would feel horrible for smoking cannabis. I was having a really hard time quitting. I weaned myself but by the time I quit I was 4 months pregnant but to be "fair" I didn't know until I was about 1 month pregnant. I have a friend who smoked her entire pregnancy and we both have really healthy & happy babies. I feel so ashamed to admit that I smoked and it feels so liberating to get it out. I love my daughter to death so I hope no one tries bashing me in the comments.
