my mum announced for me!!!

Anna • I’ll be honest
I'm livid - I'm 10 weeks pregnant, which in the uk is too early for a scan - people here usually don't announce until 12 weeks. But we told our parents early. My mum then went on an old picture of my son and commented "he's going to be a big brother." And now some of my friends who are friends with her on Facebook have seen it. So frustrated!
