Just told everyone we’re pregnant, now experiencing miscarriage right before Christmas!

So I found out about 5 weeks ago we were pregnant. I’m about 8-9 weeks along. It’s crazy because I was so sure it stuck.. we felt comfortable took announcement pictures, sent cards out to friends and family and this weekend I just started experiencing major miscarriage symptoms. Heavy bleeding, loss of breast tenderness, now a 3 negative pregnancy test. I’m so freaked out. Family is asking us to come over for presents in 2 hours and I’m in so much pain and can barely walk. I am at such a loss as to what to do.. do I just say hey I can today I’m having a miscarriage? I think they’ll all be shocked. I’m so worried about the judgement and ignorance
