Tips for hiding pregnancy until 12 weeks? 😊

Hey I just had a miscarriage dec 29th and now we are back ttc (i'm in my tww right now) and if i get pregnant I don't want my family to know because they we're all really happy at first when I told them we was pregnant with baby #2 and it was heartbeaking to tell them we lost the baby. This time I want to wait my 12 weeks and tell them with the sonogram. We always drink wine at super in family, if I don't drink a glass they will know I'm pregnant. Do you have any trick for that? 😅 I don't want to look suspicious. 🙄
