I’m 11w4d. today my sister was having a bad day so I went with her to my other sisters apartment. they ended up smoking weed. I was on the other side of the room but I was still in the room with it and I’m worried it is a problem. I KNOW it’s not good, but I felt so bad to even ask them not to do it. I’m young, they’re young, they still like to smoke and drink. I obviously can’t. I wish they’d been a little more considerate, but I was happy to see them for the first time in a while so I just didn’t say anything. what are the chances of this one time being harmful to my baby? I know it was dumb and I don’t want it to happen again, but I didn’t drive and didn’t know what to do.
