Credit Karma Study Finds 18-34 Year Olds are Looking for Stable, Well-Paying Jobs and Focused on Financial Fitness. A new survey by Credit Karma finds that contrary to popular opinion, young people really are interested in âadultingâ in pretty traditional ways. They are getting married and buying homes and cars in large numbers. Urban, suburban and rural 18-34 year-olds are starting families and using credit cards.
Your first menstrual period is called menarche (say MEN-ar-kee). It usually starts sometime between ages 11 and 14. But it can happen as early as age 9 or as late as 15. If you are a teenage girl, see your doctor if you have not started having periods by age 15. Menarche is a sign you are growing up and becoming a woman.
Menstruation is the most visible phase of the menstrual cycle and its beginning is used as the marker between cycles. The first day of menstrual bleeding is the date used for the last menstrual period (LMP). The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women, and 21 to 31 days in adults (an average of 28 days).
