Menstruation

Women who are menstruating are exempt from fasting during Ramadan — but many say they're still not comfortable eating in public. That's slowly changing as younger generations are becoming more open to discussing periods.

Girls in the U.S. are getting their first menstrual period about 6 months earlier on average than they did in the 1950s and '60s. And the number of girls starting their period before age nine has doubled. Researchers say parents can help prepare their kids for early puberty.
