Pregnancy announcement

We don’t know what to do. Originally we planned to tell our family and closed friends on thanksgiving since we thought I’d be 10 weeks, but turns out baby is measuring a week behind. We’ll be 9 weeks and 3 days on thanksgiving and we’re not sure if we should share. I’m a social drinker, always drinking wine or beer so I know it’s going to seem odd if I don’t. Should we share? I don’t think we can hold it in until Christmas and to be honest, keeping it a secret is stressing me out. I want and need my mother’s advice. This is my first pregnancy and feel so lost. I was thinking of possibly doing a a private ultrasound Monday to make sure baby is okay? Ughhhh. ☹️
