Looking for some fake drinking help

So I just found out I was pregnant today and we are so excited, however we are also a bit nervous as we had a miscarriage late January. I got a blood test done today and am getting a second one done on Monday to make sure my levels are increasing. So this weekend I have a wine night with my girl friends... we obviously don’t want them knowing yet, so how do I hide the fact that I can’t drink? Should I bring non alcoholic wine? How do I pass it for regular?
