I'm going to a wine tasting event with a few colleagues before I'm planning on telling work about my pregnancy. There's no way I can get out of it without seeming really rude. My usual trick for social events so far has been to buy G&Ts without the "G" but obviously that won't work here when I'm being handed glasses of wine... I don't drive so can't use that as an excuse. Another colleague used the antibiotics excuse before announcing her pregnancy so that would immediately ring alarm bells. Any ideas??
