Smoking

Okay so I just found out unexpectedly that I’m pregnant.. don’t get me wrong this is a dream come true but again, wasn’t expecting it. I’m about 5 weeks pregnant and I smoked weed a few times here and there before I knew I was. I feel terrible, does anyone know what could happen because of that??

Edit: of course I’m going to stop now that I know. And yes I have looked it up as well, just wanted advice from those who have been in the same situation or know about it.
