hiding pregnancy from friends and family without suspicions

hi Everyone 7 weeks 1 day still have a ways to go before I can officially announce to family and friends. the problem is there are too many events coming up where it will look suspicious if I am not drinking example mothers day and champagne brunch, drinking wine. any ideas on how to hide without people asking questions. unfortunately for me it is pretty obvious if I don't drink even just one drink. if I am at a restaurant or bar i can fake it and ask on the side for virgin drinks but wine and champagne is hard to "fake". thanks for the suggestions!
