horrible neighbor! will my baby be okay?

I'm 38 weeks pregnant and my husband and I live in a two bedroom apartment. Last night my husband went to the bathroom and comes out and asks "do you smell something in here?" I said "yeah I have been the last few nights when we leave the door shut. What is it?" Sure enough it's weed coming from our neighbor below who has a 6 year old! I was furious! Then I made the connection as to why I get horribly sick every morning when I get ready in the bathroom. We talked to the landlord and he's calling her immediately but now I'm really concerned for my baby's health. I'm not sure how long I've been breathing it in but do you think she'll be okay? Should I ask my doctor about it?
