Menstruation is the normal periodic discharge of blood mucus in cellular debris from the cavity of the uterus. The usual interval for menstruation is 28 days but this can vary widely and is still considered normal. As you can see by the the free online fertility calculator, we use the 28 day model. The duration and amount of menstrual flow can vary as well but the usual duration is 4 to 6 days. There are two important cycles that occur at about the same time. The menstrual cycle fertility calculator takes all this into account, but is simply based on the natural clock inside women. The ovarian cycle and the endometrial cycle. The ovarian cycle provides an egg for fertilization the endometrial cycle suitable site for implantation of the fertilized egg inside your uterus. Because endometrial changes are regulated by hormones made in the ovary the two cycles are intimately related. The ovarian cycle produces an egg for fertilization. There are about 2 million eggs in a newborn girl at Birth. This decreases to about four hundred thousand in girls just before puberty. All these facts are not necessary to use the baby fertility calculator however. Some women, about 25% of women, experience lower abdominal pain or discomfort on or about the day of ovulation. It is believed to be caused by irritation from fluid or blood from the follicle when it ruptures. The presence or absence of this symptom should have proof that ovulation did or did not occur.
