Some athletic women end up with shorter cycles and some quit altogether the more active they are.

Some medications, stress, and other things can mess up your cycle. You could be iron deficient and have a low blood count.

If you are talking about days in between cycles use the first day

I know that exercise can delay periods.  Try running everyday until your trip.  It might not work if there isn't enough time for your body to adjust, but I have a friend who works out almost everyday and she has very light to no period at all

It could be your cycle is changing, or your cycle got weird due to outside factors like a change in diet or stress. Look back and see if this has happened before in previous months and also look at this month and previous months to see if there are any outside factors.

I've never done any research, but I do think there is some validity to that idea.  In high school and college I used to be really good running anywhere from the 400m to 1600m.  I had a road bike and would cycle at a very high cadence to help focus on my leg turnover.  I used to cycle at 117 to 120 rpm for 15-20 minutes at a time.  Of course, it's more difficult to tell what kind of rpm you are at on a bike, so I would do this in the gym.  I believe it helps with a combination of other workouts.  It would also serve as cross training day.

My understanding is that this tactic works better with monophasic pills (the kind where the hormones are level over the three active weeks) than it does with triphasic ones like Ortho Tri-Cyclen (where each week is a different hormone level.)  That's something you might want to ask your doc about.  But I have been blessed by my two most recent doctors to do this on occasion as they don't feel there's any significant drawback to it.  I usually skip about every other period, just for convenience.  You might not be able to go much longer than that; some women will spot if they try to skip more than a couple consecutive periods.  But yes, you can do it.

Don't worry about it. It is probably that you have lots of contact with a woman whose cycle is shorter than yours and you are being drawn to her cycle. This is a normal, natural phenomenon. Don't worry.

Probably false.\nA cyclic pathway is more suitable for a starting material that is short in supply because the first molecule in the pathway tends to be regenerated. Glycolysis is the typical linear pathway and it starts with glucose which is relatively abundant in cells.\nI think this is not a very good question, though. It is open to interpretation.

If you are on Yaz, you should be having shorter periods rather than longer.  It may be that your next cycle will be easier if you have just started taking it, but if not I'd suggest going back to your doctor and asking about a different pill.

Honestly I wouldn't worry.  If it's weighing on you, then call and ask your doctor, but it's quite normal for periods to be shorter in duration and much lighter (and sometimes even non-existant) when you're on the pill.

In the US, current is set at 60 cycles and in Europe it is 50 cycles, that is the way it is made, I'm not sure you can change that after-the-fact, DC is of course direct.

The frequency is 282 cycles per second (Hz), so one cycle will take 1/282 seconds. Period is the inverse (or reciprocal) of the frequency.

Your period doesn't follow the calendar, where the months are 30 or 31 days long.  An "average" cycle ranges from 26-32 days or so.  Yours apparently is 27 days and that's totally normal.  That means that every so often it'll fall early enough in the calendar month that the next one will also be in the same calendar month.

the flow is different for everyone and so are the cramps etc. it actually takes approx. a year to get a regular flow but in some cases even longer. i would not worry about it. just let your body do it's thing :)
