I had one because it was a suspected (and later confirmed) molar pregnancy and they wanted it out straight away. Waiting wasn't an option.

Because it was molar, we couldn't try again anyway, but I feel like the d & c, despite all its risks, was a great thing to do and I wouldn't hesitate to do it again. My cycles have never ben more regular -perfect- than after it - the first AF was a bit heavy and icky, but the next three were perfect, and my girly bits just felt so healthy and "clean"

It's not for everyone, and there is still some bleeding afterwards, but especially with a late m/c, when there's so much stuff down there, I do think it's a good idea.

Good luck with whatever you choose
