So sorry to give awful details but I have had a missed miscarraige and Monday afternoon I will be having surgery to get myself sorted, so to speak.
Prospective mum will be ringing me Monday morning: I obviously don't want to tell her personal details but I cannot face arranging interviews at the mo. Also I feel a bit as if I have lied to her, by agreeing to meet with her while I was pregnant.
What can I tell her? Any idea? "Hello, I cannot talk today because I used to pregnant and now I am not and I have to have a D&C. Can we talk another day?" 
I had to carry on with business as usual in case this very fucking thing happened.
