This very first issue of Periodical explores what starkly marks the beginning of puberty for many menstruators: menarche, the first occurrence of menstruation. The issue serves as a guide for young menstruators as they navigate a time which many recall as being difficult and awkward. By talking about periods openly the issue hopes to normalize the subject and clear away the shame that unfortunately many feel and associate with it. It's a point in life that should be celebrated!
