I had a miscarriage at 17 weeks 18 months ago. It took me a long time to get over it and while I hoped to get pg again soon it didn't happen until just now (and surprised us both!). One of the hardest things about the mc was dealing with other people's reactions and telling people. I won't be telling people for a long time. At some stage it is going to be obvious but as I am overweight I can hide it longer than most!! I actually have a good feeling about this pg but also don't feel like sharing with others just yet. So I understand how you feel.
miscarriage risk is relatively low after the 1st trimester (12 or 14 wks depending on how you calculate) so i will feel safer talking about it with close friends after that. My mother lives far away but I am sure she would suspect if she was here. I literally went up a cup size between 4 and 5 weeks. To me it is so obvious! and it would be to her, too.
My kids were devastated by the miscarriage, too. They still talk about the baby that died and ask me how old he would have been, etc so I would prefer to avoid another trauma for them, too. If I did have a mc and had to explain to them why I am upset it is different from telling them and them being excited for a long time and then disappointed.
Sending positive thoughts,.....
