Sorry for your loss OP :-(. Especially at this time of year.
If you weren't given advice on what happens next or what happened to your baby, my best advice based only on my own crap experience of now 3 mc's is to go and see your GP and ask all your questions there. I found that the hospital were very much in, out, there you go and not really any use for ongoing support.
Hope that you have lots of support in real life and are able to be gentle with yourself.
