Menstrual cycle is a naturally occurring mechanism in a reproductive aged woman. The ability of a woman to identify the length of a menstrual cycle is important as a basis to determine the fertile period in the subsequent menstrual cycle. This research aimed to investigate the length of menstrual cycle of women in reproductive age. A regular menstrual cycle occurs in a regular pattern of length which can range from 21 to 35 days in adults. A subsequent cycle which occurs three to five days earlier or longer than the usual pattern would still be considered as normal. Meanwhile, a menstrual cycle which occurs twice in a month or once in more than two months would be considered as irregular cycle. The method implemented was an exploratory method through which menstruation periods of woman in reproductive age were recorded in three consecutive months. The research population was Biology students who are registered in academic year 2017. The participants were students who are registered in Reproduction and Animal Development subject. The data of menstrual period were collected from four study group which consists of 101 students. The result of data analysis on a total of 171 menstrual cycle showed that the average length of participants’ menstrual cycle was 30.08 days.
