It does both.
Breastfeeding temporarily stops ovulation, which in turn stops
menstruation -- menstrual periods are a direct result of ovulation. You
don't have periods without ovulating.

Breastfeeding doesn't always stop pregnancy, since when you start
ovulating and having periods again, you ovulate first (before you've had
your first period return). So you can get pregnant before your periods
come back, and I know people who have done so (oops). It's generally
advised not to rely on the lack of periods as absolute birth control; you
can be assured of a delay, often a long one, but eventually you might hit
it just as your ovaries get back in action.
Yeah. I have a rather surprising number of friends who have childres 11
months apart. They forgot the cardinal rule -- you ovulate *before*
that first period (generally) not afterwards! My grandmother was so
irregular, she never knew when she was pregnant until she started
growing out of her clothes!
