Thus, the brand new coming off an effective girl’s first menstrual cycle is frequently implemented from the pity and you will ambivalence (Brooks-Gunn et al., 1994; Moore, 1995; Tang ainsi que al., 2003), including because of the bad ideas (Rembeck et al., 2006), and nervousness, wonder, dismay, stress, and you may confusion (Brooks-Gunn and you will Ruble, 1982; Ruble and you may Brooks-Gunn, 1982).
