Suz - I totally understand. We made it clear to the parents not to tell anyone until 12 weeks, then my mum went back to France and told all my uncles and aunties and my grandma.... Because she felt a bit overwhelmed and needed to speak to someone...
Well in the end I just thought... She can also tell them if something goes wrong but I don't want anyone talking to me about it! I don't see them very often so it did not matter much...
It sucks but hopefully all will be well, you have seen the heartbeat etc.. The chances of miscarriage now or in a couple of week are nearly the same only a couple of percent difference.
I was annoyed at my mum cause I fear she would jinx me but I guess it's what mums do x
