Thank you, you're absolutely right.
EPU called me back, was a lovely lady. Apparently they didn't offer me medical because it's too late (I'm 12+3) so my options are wait or have the opp. She's had to provisionally book the procedure in for next Fri as that's the latest I can go (13+6) apparently before it needs to be done.
So I'm sitting here wondering if I should wait it out until then, and hope it happens naturally, or just get it over with. She's sounded a bit worried about me waiting it out to be honest, which equally scared me!
Rock and a hard place really now... I never even thought about the actually physical process of a miscarriage, just the emotional stuff. Baptism by fire I guess.
