My heart goes out to you as I welcome you to the community here. I'm so very sorry to read about the death of your precious baby. I too have experienced pregnancy losses.
There is a group called SANDS Stillbirth and neonatal death support. I( am not sure if it is Australia wide or not though, they helped me 20 years ago.
I would like to suggest you have a chat with your Dr. and ask if they know of any on line/ or support groups. If you are seeing medical people about your pregnancy, ask them if they know of any support groups. Also let them know of your concerns with this pregnancy.
One thing I had to learn was the pregnancy loss was not my fault! It is not yours either.
I would also like to suggest you look into some grief counselling.
I wrote a lot about my pregnancy loss. I wrote when I was next pregnant as I was concerned I would forget my first baby.
Another thing I did was to buy myself a ring as a symbol of my love for our child. A friend brought a statue of an angel.
It is important to not put blame on anyone, to learn how to cope with your grief, to understand there will be tears in the memories and that is okay.
My husband never saw the babies, never talks about them and doesn't like me doing so in his presence. That is okay to. He deals with it in his own way.
Hopefully knowing you are not alone in experiencing such painful memorieshelps in some way.
Kindest regards to you, from Dools
