Oh Kep, that sounds horrible. My story is very much like yours - a two week wait from finding out to having my ERPC, which I had yesterday. I was 13 weeks when I found out, so was keen to get it over with quickly.
I called and asked them to put me on the surgery list for the same day as my scan after seeing that suggested on here, which they were lovely about. They moved my scan forward to 8am to make sure I'd get on the list, and said that if the scan shows anything that changes my mind it doesn't have to go ahead. This was actually last week (1 week post original scan), the scan showed some growth of the foetal pole so surgery cancelled I was sent home for another week to be scanned again yesterday, when they found it was definitely not growing and the surgery went ahead.
I was bleeding but not a lot and didn't have much hope it would happen naturally any time soon. Two weeks is a very long time to wait with this knowledge. And having a definite date for the surgery helped me to prepare for what would happen and when, move work around and let my boss know how long I would need etc. I was bleeding a little and terrified it would suddenly get worse at work, thankfully I was able to work from home, which was ok for a week but wasn't something I could have continued if I'd miscarried naturally over the course of several weeks.
The ERPC yesterday was absolutely fine, the anaesthetist was absolutely lovely and held my hand as I went under, I was up and about really quickly and other than feeling a little woozy today I'm feeling really well. I was into surgery at 11 and home by 3.30. Not in any pain and hardly bleeding at all.
I should have been 15 weeks now, so I just wanted it finished so I could move on. Stupidly, I can't stop calculating age gaps with my toddler and possible baby age at my brother's wedding next year ("so if I conceived again by the end of April it'll be a three and a half year gap, that would be ok, they'd still relate to each other" "if I conceive by May I'll have given birth long enough before the wedding to have breastfeeding established" etc etc) and that's part of the time pressure I'm feeling. Mad I know.
