I'm 18 and 31 weeks pregnant. I'm hanging out with my friends and their boyfriends, they are playing beer pong and drinking. They aren't being obnoxious. But I was just wondering if since I'm pregnant is it wrong for me to be here. I'm not drinking or anything. Just sitting on the couch watching them play and talking to them.
