Hi I'm new, so I hope I'm doing this right!
But I totally understand how you feel, completely! I'm only 6 weeks and joined here for people my age as I don't really like or trust any of my peers around here.
But yeah when I found out I told my adopted dad and he told my mum. They were over the moon especially my mum. Then my mum told my real dad and brother, I wasn't too happy about that but he was pretty chilled. Then he told my grandma who I think nearly had a heart attack of happiness and she told pretty much the entire neighborhood and she is already talking about wanting to buy the pram -__-
It's like 'guuuuys, calm it down a biiiit'. I'm like you and just terrified of miscarage and didn't want to start planning anything until at least half way!
My friends at college luckily don't know as it's half term and I hope to keep it like that. I just hope the constant puking doesn't give too much away haha.
But I think kbwebb is right, if it's going to happen it's going to happen.
Good luck, congratulations and I hope you have a happy healthy 9 months
