Getting Your Menses(Menstruation/Periods)

Do you have a complete understanding of a woman's reproductive system? Ok, let me tell you a little phase of our live as a woman. The start of periods is known as menarche, while girls begin to go through puberty usually found between the ages of 9 up 13 gets her first menses period. Menarche happens because all the parts of a girl's reproductive system have matured and effort simultaneously.

The reproductive system release the hormones in their bodies, like estrogen and progesteron which responsibility in order menses every month. In other side, the hormons motivate new physical development, such as growth and breast development. Menses is a major phase of puberty in girls, it's one of the many physical signs that a girl is change into a woman.

And than, what happend in our reproductive system every month after menarche?

Stimulated by gradually increasing amounts of estrogen in the follicular phase, discharges of blood (menses) slow then stop, and the lining of the uterus thickens. Follicles in the ovary begin developing under the influence of a complex interplay of hormones, and after several days one or occasionally two become dominant (non-dominant follicles atrophy and die). Approximately mid-cycle, 24–36 hours after the Luteinizing Hormone (LH) surges, the dominant follicle releases an ovum, or egg in an event called ovulation. After ovulation, the egg only lives for 24 hours or less without fertilization while the remains of the dominant follicle in the ovary become a corpus luteum; this body has a primary function of producing large amounts of progesterone. Under the influence of progesterone, the endometrium (uterine lining) changes to prepare for potential implantation of an embryo to establish a pregnancy. If implantation does not occur within approximately two weeks, the corpus luteum will involute, causing sharp drops in levels of both progesterone and estrogen. These hormone drops cause the uterus to shed its lining and egg in a process termed menstruation(Wikipedia).

An Normal womans usual menses cycle lasts for 28-30 days. although, cycles can vary indefinitively. Some women may have regular five week cycles, others may find that the number of days can vary from month to month. Women may experience menses cycles of anything from 20 to 35 days. But, if you have more than tree month cycle, it's abnormally menses cycles.

If you are likely to become pregnant, you may intercourse takes place between day 8 and day 18 of yours cycle (28-day cycle). But, if you unlikely to become pregnant you may intercourse takes place during the first 8 days or the last 10 days of her cycle. because it's the timing of ovulation and the lifespan of a male sperm.
