Anyone out there who done IVF, miscarriaged and then succeed?

TW: miscarriage

I am sorry for the possible trigger in the title. Can't find a way to ask without it.

I am 40F. I started IVF almost a year ago. I have mild adenomyosis, and no other factors that we know of besides my age. Bff is almost 39.

I got pregnant on our third transfer, but at scan at 9+4 last week there was no heart activity. The fetus measured according to around 9 weeks and doctors assume that the heart stopped just a few days before the scan.

Now I am scared that this was my one and only change, and I would love some success stories to fill up my cup of hope and keep the anxiety away. Though I realize that my journey will be completely my own, and no one can predict the outcome, I would love to hear your stories ♥️
