Male poster chiming in here…
Sorry for the slight hijack, but I remember reading that you’re born with all the eggs you’re going to have. If that’s so, does this mean that women on a shorter cycle are typically going to reach the menopause more quickly than if their cycles were longer?
Thanks…
Xerxes, women who have gone through menopause still have plenty of eggs left, they just don’t ovulate anymore.
Another 26 day person here, although I’m usually on the pill. I never noticed the shorter cycle until I started counting while were were trying for a baby.
Whenever I start cramping (meaning my period is coming)my sister gets very irate because she knows she’ll start in the next day or so.
another short cycle here. When I’m on the pill, it’s 26-27 days. When I’m not on the pill, it can be 21-25 days 
Good thing I’m back on the pill now.
Xerxes’ question brought up a question I’ve always had, and maybe a gyno can answer it: do women who have several pregnancies go through menopause later in life because of all the time that they aren’t ovulating? (due to pregnancy and breast feeding).
Just curious.
Well, my average is 29 days, from beginning to beginning. But mine does this lovely jump up to 35 days then gradually decrease back to 25 days over five to six months. Makes for fun times with the bf when it decides to jump from 25 back to 35.
In the last two years I’ve had one that was exactly 28 days. My last three were 25 days.
GKW, it’s not an old wives tale, the thing about sychronizing periods. Menstrating women who spend alot of time together [co-workers, family, roommates, teammates] will be exposed to each others pheromones**. Whomever has the more “powerful” pheromones can occasionally influence another woman’s body to slowly adjust it’s cycle to match.
Story: A girl on my college rowing team was on some kind of birth control, and before she joined the team had been enjoying a lovely 45 day period. About one month or so into the season she said she’d had two periods in three weeks but was not back to the normal length [could have most likely been something other than being around alot of other girls]. This inspired another girl [who was not on b.c.] to reveal that she too had experienced a big shift in her period.
The most practical theory I’ve heard for this is that if all the women in a group [think cave-man days] get their periods at the same time, they’re fertile at the same time, and might give birth around the same time. They then might be able to help each other with the rugrats. Or it could just be one of those weird phenomena like why labor is so different more many different women. I’m guessing here.
**I can’t recall if it’s been established that humans produce pheromones or not, but i’m using the term anyway.
