How do normal periods occur?
Several factors work together to produce normal periods. The ovaries (glands situated beside the uterus) produce an egg every month. This developing egg produces a hormone (estrogen) which thickness the inner layer of the uterus. The egg matures and then ruptures and another hormone (progesterone) is now produced. This hormone scrapes off the entire layer which has been built up earlier and throws it out in a controlled manner and periods result. Since the whole process is well controlled by the specific hormones, the bleeding will occur at the expected date and will last for a finite time. The whole process of development, ripening and breaking open of the egg is called ‘Ovulation’. What happens if there is no ovulation? If the egg formation does not occur properly the entire process occurs in an uncontrolled fashion. The secretion from the developing egg does not occur in a normal manner and hence the development and discarding of the layer of the uterus does not take place properly.
