Giving up Marijuana

Anyone else a regular weed smoker? I was for 3 years, but as soon as I saw the positive sign I quit (which was only 5 days ago).  I know some women who smoke weed throughout their pregnancy, but I don't feel like there's enough research on it to say that it's safe. The websites that actually use scientific research all seem to say that it's not ideal, but not related to miscarriages or birth defects. But I still don't feel right using it during pregnancy. Anyone else in my boat?
