Dogs have their first estrus (heat cycle, "period" etc) where they can get pregnant between 6-18 months usually. They continue to have them once or twice a year until they die, they never lose their fertility (unlike human females who undergo menopause.)
The only way to stop the cycle is to get her spayed (surgically sterilized.) It's also good for her health because older intact females are prone to pyometra, a life-threatening infection of the uterus, which spaying prevents completely.
While older females CAN get pregnant, it's a bad idea because they might not have the strength for giving birth and the body reserves to make enough milk for the puppies.

If you're looking to breed, at least wait until she's fully grown and matured. Humans can get pregnant at age 12, sometimes even earlier, but that doesn't mean it's good for them.
This means waiting until she's at least 2 years old. This is also the age that health tests such as CERF and OFA can be certified, and they *are* important because they help to tell you how likely she is to pass unhealthy genes onto her offspring. (They're not the only tests that need to be done, though.)
If you are looking into breeding, do your research. I mean, really do your research. There are several websites (including mine, cookiemiller.tripod.com) that lay out the basics and give you an idea what breeding a dog involves, and there are books at the library as well. But book-learning is not enough, find yourself an experienced mentor, too.
If this was not your purpose in asking this question, ignore and just read the first person's answer. Heh.
