I feel a need to inform you of the facts.


What goes on in that miraculous body of yours in any given 28 days? Read on.
The very short version:
Egg ripens. Egg leaves ovary. Egg travels down the fallopian tube toward uterus. If egg goes unfertilized, you get your period.

The long version:

Day 1: Your period starts.
For whatever reason, Day 1 of your cycle is counted as the first day you see that telltale spot of blood. Generally this happens every 28 days or so (though like everything else, cycles vary by person). If in that time the egg in your uterus does not get fertilized by a sperm, the egg disintegrates and is expelled from your body. On Day 1, your cramps are probably at their worst as your uterus contracts to push out the egg and the cells and blood that nurtured and fed the egg as it grew.
Day 1 to 14: Called the estrogen phase of the menstrual cycle.
The day you get your period, your body's estrogen level is at its lowest, and from there it starts to go up. Your brain sends a signal to your pituitary gland, which releases a hormone called FSH, or Follicle Stimulating Hormone. When the follicles in your ovaries sense the FSH, they munch happily away at it. This makes them produce estrogen. The estrogen causes one of the hundreds of tiny, slumbering eggs inside the ovaries to start developing.
Day 2-5: Bleeding, bleeding, bleeding.
Less so each day.
Day 6: Egg be gone!
The bleeding has usually stopped by now. Meanwhile, the stimulated, FSH-happy egg is maturing and getting ready for ovulation.
Day 7-12: La, la, la, you go about your life.
The egg, meanwhile, is growing, and the follicle is expanding to accommodate it. The follicle is still producing estrogen, which makes the lining of your uterus nice and puffy and spongy--if you were to get pregnant, this lining would provide the fertilized egg with the food it needs to grow into a baby.
Day 13-14: Ovulation!!
The new egg has reached maturity and exits the follicle just rarin' to go. You might actually feel it when you ovulate--a little twinge or cramp in your lower abdomen or back. It's called mittelschmerz, which is German for "middle pain." You may see a teeny drop of blood. This is probably fine, but if you're concerned, see your doctor. Your body temperature rises up to one degree and stays up until you get your period. The natural mucus covering your cervix (the entrance to your uterus) starts to thin out so the sperm can get through and fertilize the egg.
Day 15-18: The egg takes a trip.
The days when the egg travels down the fallopian tube, usually Days 12-17 or so, are when you're most likely to get pregnant. While the egg's in the tube, your estrogen level drops again and the follicles begin producing progesterone. Unsurprisingly, this is called the progesterone phase.
Day 19-20: Your uterus prepares for pregnancy. The progesterone makes the fluid around your cervix thicken up again and tells your uterus to build up the protein, sugar and blood necessary to nourish a fertilized egg. Progesterone is a big ingredient in PMS, so you may start feeling a little crabby and your skin might break out a little.
Day 21-28: The progesterone and estrogen are still increasing, so you may feel soreness in your breasts, bloating and food cravings. One theory holds that your body hankers for carbohydrates because they'd come in handy if you were indeed pregnant. You might want to avoid salt right now, because if you're bloated already, salt will make you retain even more water. If the egg remains unfertilized, your estrogen and progesterone levels drop, and both the egg and the endometrium dissolve. Cramps begin, bringing you back to Day 1: Your period starts.

Good effort, but there are new teens asking the same questions every single day, doubt this will lessen the sameness involved.
