There have been many many studies that show that smoking cannabis while pregnant or breastfeeding can lead to detrimental effects of the newborn. There has been one from over 20 years ago from Jamaica that seems to show no negative effects. All medical organizations specifically do not suggest cannabis while women are pregnant. The main issue here is, are you willing to take a chance on harming your unborn, or newly born child? When you only have yourself to think about and be responsible for, the answer is obvious.
