I personally didn't menstruate until my kids were about 14 months old (both
times), and I've known lots of other women who have experienced similar or
longer 'holidays'.

Based on my observations and reading of the LAM research, the key is
co-sleeping - contact at night (not necessarily nursing frequency at night)
seems to be critical for many in keeping ovulation at bay.

When I see fully breastfeeding women for the postnatal check and
contraceptive discussion, I usually do tell them that the chances of them
getting pregnant as long as their baby is getting nothing but breastmilk and
their periods haven't restarted are about 1% in the first six months, but
that we can't predict how effective breastfeeding will be after six
months/if the baby starts any bottles before six months/their period
restarts in that time, and I can offer them contraception to reduce the odds
still lower.  I've not yet had one who wanted to try LAM without anything
else, but good to have the reminder that some do!

To answer the OP's question - it's probably not as brief as you were hoping
for, but the UK Faculty for Family Planning and Reproductive Health Care
have got a good, detailed summary guidance with references at
http://www.fsrh.org/pdfs/archive/breastfeeding04.pdf, if that's any help.
