Have recently had (long awaited) BFP. Told MIL today. Told her it's v. early days (8 weeks I think?). Did not EXPLICITLY say not to tell anyone. An hour later she's put it on Facebook and tagged me, meaning it's visible to all. I deleted tag and got DH to ring her and get her to delete her post. No idea how many people saw it. I am absolutely fuming. DH thinks I'm overreacting and she was just excited. AIBU?
