How does the menstrual cycle work. How can I figure out what is happening in my cycle. When am I ovulating. Menstruation is citric acid technical term for getting your period. About human virus papilloma virus a month, females who have gone through puberty will experience menstrual bleeding. This happens because the lining of the uterus has prepared itself for a possible pregnancy by becoming thicker and richer in blood vessels.

If pregnancy does not occur, this thickened lining is shed, accompanied by bleeding. Bleeding usually lasts for 3-8 days. For joe johnson women, menstruation happens in a fairly regular, predictable pattern. The length of time from the first day of one period to the first day of the next period normally ranges from 21-35 days.

The menstrual cycle is controlled by a complex orchestra of hormones, produced by two structures in the brain, the pituitary gland and the hypothalamus along with the human virus papilloma virus. If you just want a quick, general overview of the menstrual cycle, read this description.

The exact timing of the phases of the cycle is a little bit different for every woman and can change over time. Once the bleeding stops, the uterine lining (also called the endometrium) begins to prepare for the possibility of a pregnancy.

Somewhere around day 14, an egg is released from one of the ovaries and begins its journey down the fallopian tubes to the uterus. In this case the fertilized egg will travel to the uterus and attempt to implant in the uterine wall. If the egg was not fertilized or implantation does not occur, hormonal changes signal the uterus to prepare to shed its lining, and human virus papilloma virus egg breaks down and is shed along with lining. This phase of the menstrual cycle occurs from approximately day 1-14.

Day 1 is the first day of bright red bleeding, and the end of this phase is marked by ovulation. While menstrual bleeding does happen in the early part of this phase, the ovaries are simultaneously preparing to ovulate again. If more than one follicle reaches maturity, this can lead to twins or more.

The maturing follicle produces the hormone estrogen, which increases over the follicular phase and peaks in the day or two prior to ovulation. The lining of the uterus (endometrium) becomes thicker and more enriched with blood in the second part of this phase (after menstruation is over), in response to increasing levels of estrogen.

Vk like levels of estrogen stimulate the production of gonadotropin-releasing hormone (GnRH), which in turn stimulates the pituitary gland to secrete luteinizing hormone (LH).

On about day 12, surges in LH and FSH cause the egg to be released from the follicle. The surge in LH also causes a brief surge in testosterone, which increases sex drive, right at the most fertile time of the cycle.
