Is 37 day cycle is a normal period or irregular?

Answer 1

Depends...per WebMD (http://women.webmd.com/tc/normal-menstrual-cycle-normal-menstrual-cycle), "The menstrual cycle is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is often cited as the "regular" cycle length, only 15% of women actually have such a cycle." * A teen's cycles tend to be long (up to 45 days), growing shorter over several years. * Between ages 25 and 35, most women's cycles are regular, generally lasting 21 to 35 days. * Around ages 40 to 42, cycles tend to be the shortest and most regular. This is followed by 8 to 10 years of longer, less predictable cycles until menopause.
