You can still get pregnant while breastfeeding even if you aren't having a period. After I stopped breastfeeding with my son at 5 months due to PPD and the meds I had to take to treat that, I didn't have a period for 3 more months, but I was ovulating.
If you don't get pregnant after ovulating, you menstruate (bleed for half a week or so out of a month). The ovulation is the important part, and that is one reason why you don't want to have sex before you menstruate, because you might start ovulation and not know it, and get pregnant without ever having menstruated.
