Clarity I know what you mean and don't blame you. On the plus side, a later scan will show a more developed baby on screen, but I completely get about wanting to tell people at certain times etc. I've avoided paying for a scan (though I got s reassurance scan at 8 weeks) but suspect I'll cave and book one about 16 weeks to find out the gender!
I was desperate for my scan before the weekend because I've got a family party where it would've been easy to tell everyone, but actually in hindsight I'm quite glad because I don't think OH and I could cope very well with 60+ people all knowing at once when we're still anxious!
Loads of people know already anyway because I've had a birthday and I normally drink wine like a fish. I couldn't hide it so just told people but said it's very early days.
Woke up today at 12 weeks and feel fresh as a daisy! It's a nice feeling, just hoping it's because the placenta has taken over etc. 4 days until scan and I think I can just about hold it together until then...
