how long does a woman's menstrual cycle last? 28 days or can it last longer?
For the regulars, it's a 28 days cycle. However there are women (like me) who could have a shorter cycle, I do 25 days sometimes...and I think I do ovulate less than 14 days after the first day of my period...
They say 28 days, but I don't know too many women who have the exact 28 day cylce. Of course 28 is just an average really. My cycle is more like 37 days.
