Hey @Sparklesurprise29 I'm sorry for your loss. I would suggest you could call the EPU team and ask if there is anything for you to do before Thursday. When I had my confirmation scan, they took bloods then (but I didn't miscarry at home, it was in a&e so they took bloods then too).
If possible, the best thing you can do right now is rest and talk to whoever will give you and your partner that emotional support you need right now.
