So sorry that you are going through this.
I can only tell you how it affected me. I had an ERPC two weeks ago (MMC discovered at 12 week scan, baby had died at 6 weeks, and I had no idea - felt/looked very pg). For the first couple of days I felt ok but spaced out, mainly because if the anaesthesia in my system. I had almost no bleeding, but lots of stomach cramps (like really bad period pain). Paracetamol didn't touch it, but codeine worked well. Panadol Night Pain was a godsend for the first few nights. 
. I felt sad, but not overly emotional, more stunned really.
48 hours later was when the emotional side of things really hit. Every little thing made me burst into tears (burning the toast, anyone saying nice things). I was a blubbering wreck for a couple of days, tbh. I had been warned by the hospital that this would happen, and they weren't kidding! I think it was a combination of the anaesthetic coming out of my system and a surge in hormones.
I spent most of days 3-5 afterwards in bed or lying on the sofa under a duvet feeling sorry for myself 
. I also got an infection at 48 hours post-op so felt really unwell with that and needed anti-biotics, but I know that's the exception rather than the norm.
A week later I felt physically fine, just very tired, and have felt very tired even until now (2 weeks post op).
Be really gentle with yourself, don't try to do too much, and take as much help as you can get. I'd told only two people that I was pg. but I told more about the miscarriage and their support was invaluable.
