A healthy and regular menstrual cycle is considered a vital sign of good health for premenopausal women. A normal menstrual cycle should occur every 25-35 days, (give or take a few days on either end), with the average cycle length falling at about 28 days.

I was gasping for air with the whitewater waves rising in front of me, crashing over…
