Oh my darling, your pain is unimaginable. Your little Paige was beautiful, you did make a really lovely little angel, and such a good weight too.
I lost my little girl at 40 + 5 in March 2015. The same as you pretty much, I didn't notice any movement as went in to be checked (just on the safe side) and nothing. That scan to confirm and the millions of questions about what you'd like to do etc. even now it makes me shake to think about. Please, please talk as much as you can about it. To whoever you feel comfortable talking to. I am two years down the line. I can get through more better days now than at first, but those periods of real low still hit and start to get lonelier as time goes on and everyone thinks you should be over it 
I completely inderstand the need to fill those empty arms. When we left the hospital the midwife said she'd see is again next year. At the time I thought she was mad and cruel. But I wasn't prepared for that desperation to fill those empty arms. I think looking back I wanted to fix everything and get it back on track.
I did fall pregnant and I now have a beautiful, healthy baby boy. The pregnancy was hell, so please prepare yourself and enquire about what mental health support the hospital will offer. You will deal with your loss but also the fear of that pain all at the same time. It is like standing on top of a cliff you have already fallen off one. You can't quite believe you are there again and you remember the pain of every rock you hit against on the way down.
I struggled when I found out my baby was going to be a different sex for the little one I lost. I was convinced I'd have another girl, I just wanted my baby back. The realisation that actually that baby was not going to be the baby I lost was like grieving all over again. It sounds daft but I guess only those who have lost will understand the desperation to get your baby back.
As soon as my little boy was placed into arms, alive and well I was so relived. The most important thing was he didn't change how I felt for her, which was one of my worries. I loved and missed her just the same. But I also loved the little boy on my arms. He brought with him a whole new reason to be happy again, I guess a beautiful balance to the sadness I am honorific to feel fory angel girl.
Please please please take good care of yourself.
for you and 
for Paige.
