Jane - I am still so sorry. I have a funny feeling that I have something here from you (I think??? ) and every time I look at it sitting in the tree I think of you
I imagine the dr at casualty wants to ensure you are going to get the adequate follow up care. My GP wanted to see me a few weeks after the event to check my mental state mainly. As you are naturally miscarrying, its probably a good idea for them to keep an eye on whats going on inside you to ensure a D&C isn't needed.
As for what helped - well a jolly big bottle of wine was very beneficial for me, but everyone is different.
Use some heatpacks, dont be afraid to take pain relief as its needed, and try to get some rest.
