Hi - I had a private scan nearly 2 weeks ago and showed baby hadn't developed. As I was unsure of dates, it could have been too early to see baby, but that's highly unlikely. I'm booked for a scan this Thursday evening. I had a mmc 2 years ago (baby stopped at 8 weeks, but not discovered until 12 week scan), and would rather wait for things to happen naturally this time, but does anyone know how long it's safe to wait, rather than having an ERPC?
