Conceiving straight after miscarriage?

S
I just went through my first miscarriage yesterday at 11 weeks. I'm devastated, but we also really want to try again as soon as possible.
Has anyone had success conceiving (and going the full term) on the first ovulation after a miscarriage, before having the first period?
My doctor suggested waiting one month before trying, but we don't use contraception, so I'm a little bit torn as to what to do!
