Juan yes all round shitty shit shit!
It was strange waiting for that BFP, I was surprised that it was still strongly positive 1 week following medical management (couldn't help but test!).
My biggest fear was still testing positive weeks later and then needing an ERPC, which is something I wanted to avoid in the first place.
Also, my medical management was long/drawn out, relatively.
I didn't pass everything at the start- the "main event" occurred over a week after the pessaires went in- the day I was due back to work!
Also, I had to push away thoughts that this might be the last BFP I would see. I reasoned that I'd fallen pregnant quickly twice before, no planning or anything- it would happen again v soon!!
So I felt quite happy & almost excited with the BFN- we could just get on with things again after losing 13 weeks or so on a pregnancy that was never going anywhere.
Fast forward to now, almost 1 year post MMC and we are still trying 
Cycle 11 now
Wondering if that BFP was the last one I'll ever see!
