I'll be 11 weeks at Xmas and will be telling me grandparents, uncles, aunts & cousins as it isn't often we all get together.
Our situation us a little different though. When I first found out I was pregnant at 5 weeks, I had to tell my manager straight away. I work as airline cabin crew and you have to stop flying when you find out your pregnant and get put in ground duties instead. You get removed from everyones roster and it is blaringly obvious why.
So within a week, my colleagues all knew. 40+ people right there in a matter of days.
Knowing that this many people, some mere acquaintainces, knew of my pregnancy helped give me perspective on who to tell before 12 weeks.
We told our mums, dads, brothers & sisters as well as best friends within the 6-9 week mark.
I figure telling people won't make something going wrong, if the worst happens there are so many people that know but there are ways of getting the word spread so I wouldn't have to do it personally.
I think the stress of trying to hide it can actually be quite immense, so I feel pretty relaxed and happy that my secret is out early.
Good luck and merry xmas! Xx
