@Linkoln heya and welcome! I'm 9 + 5 according to an early scan I had privately so we're not far off each other!
It's really hard to keep positive, especially after you've experienced what you have, my condolences to you. When is your scan due? Are you in a position where you can pay for a private scan for some intermittent relief?
Have you had your Midwife app cos they could refer you to the perinatal mental health team like they are doing with me.
I worry about symptoms too, but I have learned that they fluctuate on a daily basis and my midwife told me we have to try and live in the moment and enjoy the now rather than thinking what if. I won't tell you not to worry because you probably still will but just need to find ways around not fixating on a worry and rationalising them.
I completely empathise with you though as I think the exact same way. It's a worrying time but this forum is good for support and advice. I also downloaded an app called tapping solution and there is a pregnancy section on there. Also another poster on here said on the mindfulness app there is a pregnancy section too.
Lots of love to you xx
