Firstly, you haven't jinxed anything, i constantly thought the same, with different things but look at me now.
Secondly, I completely understand where you are with the scan. I had never had a good early scan until this pregnancy ( and I'd had a few) so there is no way of feeling confident about it, youjust have to go and do it. Alternatively, I think it was Joeve who didn't even have one at 7 weeks? It depends if you want to know the good or the bad news at seven weeks or prefer to live in ignorant bliss for longer. I bet time is ticking by very slowly for you! Theres no reason to think you haven't got a sticky bub on board, but Iknow when you have a m/c before nothing reassures you. Crossing all my fingers for you for your scan, and will send positive vibes .
Your mum is a classic- mother's intuition hey! Shame she ruined the surprise, is she going to keep quiet?, my mum is a blabbermouth so I struggled in the early days.
Also, i don't know if you have symptoms or not but at your stage I didn't have any yet so don't stress about that.
keep going Vic, we are all egging you on!
