Marijuana and morning sickness

Hi there

I have been a daily marijuana user for the last 7 years, to help cope with insomnia and digestive issues. My husband and I have been trying for a few months and just got the positive news! We couldn’t be more thrilled. I was curious if any mother’s used marijuana throughout their pregnancy or if anyone has literally ANY information on using marijuana while pregnant and if it is deemed safe at all. Information online is so inconclusive. I don’t want any judgment on this post as I have not smoked since finding out I was pregnant, but more so curious if smoking a little before bed to be able to fall asleep will cause any harm in the first trimester. Any advice?
