I lost my 1st baby at 22 weeks. I had had signs that things weren't right which were missed by my GP. I was admitted to the labour ward and told by the doc that I would probably loose her in the next 3-4 days. I had to just wait and watch it go wrong.
22 weeks is too young to be able to survive, so I knew that there was no chance. The midwives kept on checking her heart beat and it was fine. I felt so sad because I knew it made no difference.
Finally, on day 5, I wanted to go for a poo, and snook out of my hospital room (husband was in there with me asleep it was about 05.00) I was on the loo and I just felt the baby coming out. I really panicked, and kind of pushed it back in. I went out into the corridor and screamed and the MW came and took me back to the room. When they examined me, they couldn`t see the baby and said it must have been a poo. 
Anyway, a couple of hours later, I did give birth to her, and she lived for over an hour. Sadly I was unaware of this. The midwife ran out of the room when I was giving birth because she was upset. She was sent home. I had discussed with her what I wanted to happen when I gave birth and because they said the baby would be dead, I asked if she could be taken away until I was ready to go and see her. When I gve birth they were stood holding the baby and i said take it away, thinking it would be dead as I had been told. She was alive in the next room and I didn't know.
We were reasured that she was held by a MW.
I did go and see her later, and actually felt proud, she was lovely. I will never forget the feeling though when I kissed her and she was cold, it was awful.
The Post mortem showed that she was perfect, I had an infection in my womb which caused me to go into labour.
That was 5 years ago. I can honestly say that I am now "over" it. It was very hard, but my husband was fantastic and so supportive. It was very hard initially, but it does slowly get better. It was a few months ago, I was thinking about her (Emma) and I just realised that I was healed. I will always love her, and I feel she is part of our family, but the pain is now bearable.
I now have a 3 year old daughter and a 1 year old son, and I am 35 weeks pregnant with another girl. Wait for your post mortem results, and if there is a chance that you can get pregnant again, go for it. It won't take the pain away or replace your baby, but it will really help.
