Yes, all humans and primates (all mammals) apart from rabbits have a fertility period. This is a time the female is approachable and ovulating. In primates it is obvious because the genitals usually redden. Whereas, human females have number of significant indicators of ovulation, ranging from bloating to mood swings.
The period of fertility in primates varies from 29 days to 37 days (retrieved June 5, 2019 from http://pin.primate.wisc.edu/aboutp/anat/menstrual.html).
Female (humans) the typical menstrual is every 28 days lasting for 4-8 days (retrieved June 5, 2019 from https://www.womenshealth.gov/menstrual-cycle/your-menstrual-cycle#3).
