So I went to a party today at my friends’ house at 21 weeks pregnant. They don’t smoke weed in the house when I’m there because I’m pregnant, but they forgot about it and smoked weed in their kitchen until I walked in. They then went outside to smoke and I went outside to get fresh air for probably 20 minutes. I ended up going back in the house for an hour until I left to go home. The windows and doors were open. I feel like an idiot for going back in the house. Does anyone know if I should be concerned about this exposure?
