The menstrual cycle

The cycle differs mostly in 3 phases:

Phase 1 – Phase preovulatory or follicular

Start on the first day that we need of the absorbent due to blood loss and ends the day before the occurrence of ovulation.
This first day is called 1pm (pm = post menses) and the subsequent follow the numerical order, then 2pm, 3pm, 4pm, etc. …

The follicular phase is not time certain and fixed, but its length may be subject to variations of great extent and is so named because in this phase, the follicles, which are vesicles containing oocytes.

During menstruation begin to accrue a certain number of follicles until, driven only a hormone called follicle dominant choice for the continued growth, while others are intended to eliminate.

The dominant follicle will increase its size by about 2 mm. day and burst around 20-25 mm., producing the egg and becoming corpus luteum with the main activity of production of progesterone, vital for the success of the system.

At this stage, because the endometrial mucosa, stimulated by progesterone made by the corpus luteum, thickens and grows about 1 mm per day, up to the moment of ovulation with a thickness that varies between 8 and 12 mm. Thickness other than this range may hinder implantation.

STAGE 2 – Phase ovulatory

90% of fertile women are able to observe, during ovulation, the onset of ovulatory mucus. This sign is of particular importance to determine fertile and infertile days because it reacts in real time to hormonal changes but should not be considered alone, as such, is particularly illustrative only when compared with the parallel course of temperature.

As long as there is mucus or that recurs after a brief interruption to a period probably should think long and fruitful TB (BBT) does not increase after the cessation of mucus, you should consider the possibility of additional fertile days.

Only the rise of TB indicates that the fertile period has elapsed, then stopped when the mucus, have had three heat rises, which, each considered separately, were the highest of the six previous lower temperatures.

From this it follows that it is fertile, with fertility increasing, three days before ovulation with a maximum on the day of ovulation and fertility is fertile but with decreasing fertility within three days and at elevations of up to three terabytes.

STEP 3 – post ovulatory or luteal phase or luteal

The rise in temperature temperature concomitant with the end of the mucus is the most important evidence of the corpus luteum and then ovulation occurred. Ovulation sharing with the count, and then the day of ovulation supposed to be counted as day zero bit (After ovulation) and the following days 1, 2, 3 … bit – that constitute our luteal phase.

A normal luteal phase is from 11 to 16 days, is always equal to the same woman but may vary from one woman to another. One day more or less food should not be confusing because not knowing when, exactly, has ovulated, it is likely that there are these small differences.

For example: you have a luteal phase of 11 days, but there are 11 months in which the accounts and other accounts in which 10 or 12. This depends on the ovulation and that of the next menstrual period. is likely that in that month you may have ovulated at night and the next morning did not succeed, for obvious reasons, have already rising TB and menstruation have arrived in the evening instead of morning.

Be careful, because any days of premenstrual spotting should never be included in the new cycle, but part of the previous cycle. For instance: if I have spotting today will, for example, my 28pm tomorrow and if I need of the absorbent can begin to count from 1.
