Your cycles may change through your life so during the 5 years you have been on the pill they may indeed have got shorter. I went on the pill at 19 with a 36 day cycle. 11 years later when I came off I went back to 36 days for the 5 months before I became pregnant. After I had the baby my cycle was 28 days for the 2 and a half years before my next pregnancy.
The 14th day is when you ovulate in a 28 day cycle. Most cycles run 28-38 days and not shorter. If you are having a shorter cycle go to the doctor this isn't normal.

Yes, there is a 21 day menstrual cycle. The typical cycle is 28 days but everyone is different and some people may have shorter menstrual cycles than this.
Assuming you are asking what has a shorter wavelength 1 Mhz or 1 Ghz, then the answer is 1 Ghz. But the way the question was phrased, Mhz or Ghz, well 1000 Mhz is = 1 GHz. Note that 1 hz is just 1 cycle/sec. 1 Mhz is 1,000,000 cycles/sec and 1 Ghz is 1,000,000,000 cycles/sec. So to fit 1000 cycles in one second (as compared to 1 cycle in a second) the cycles have to be shorter (faster up and down sinusoidal wave).
With advancing age does come shorter menstrual cycles, and furthermore menopause, but that is not the only reason why a woman can have a shorter cycle. There are studies that show that high caffeine intake shortens menstrual cycles. Shorter menstrual cycle indicates a less of a chance of getting pregnant.
All biogeochemical cycles involves living organism. Occurence of chemical change to bring about changes within the cycle.
The rock cycles are used to understand how rocks are made and how they change from metamorphic to sedamentary and so on. It is a chart to explain it.
The length of the typical menstrual cycle is 28 days. Everyone is different, some people may have longer cycles and some may have shorter cycles.
Most often, no. The supposed "normal" length of a menstrual cycle is 28 days but most women will have shorter or longer cycles.
The average menstrual cycles lasts 28 days - but different women may experience different menstrual cycle lengths, and cycles can change throughout a woman's life.
Yes, your menstrual cycle will change whenever you've been pregnant - whether that pregnancy ends in abortion, miscarriage, or childbirth. It takes time for your cycles to return to normal after pregnancy, it can take up to a year for the cycles to regulate fully again.
Nothing happens if you start your period a week early. Menstrual cycles can be different from one cycle to the next, up to a weeks variation is fairly standard. All this means is that your last cycle was a wee shorter than normal, either you ovulated sooner or your luteal phase was shorter.
