At the beginning of the menstrual cycle, a few follicles develop. Only one dominant follicle matures, called Graafian follicle. It opens and releases the egg: it is ovulation. At that moment, the follicle becomes a corpus luteum. The egg enters the fallopian tubes, where 3 to four days it moves through the uterine cavity. If it is fertilized, it implants there otherwise the egg lives for about 24 hours, and the corpus luteum is secreted for 12 to 14 days. Then come the rules and a new cycle begins.

What to do if you forget to pill?
The combined oral pill is very effective but one in 10 women forget at least once in the month! Gold mini and minipills impose a decision very regular: an hour's weight in the timetable only. Normodose's pills, they, except derivatives of several hours. In addition, the interruption of seven days to "see the rules is an interruption limit. An additional day off and the eggs take the opportunity to come to fruition. The risk of pregnancy is not well controlled.
Emergency contraception (RMS) is desirable if there was sexual intercourse in 72 hours before oblivion, especially if oblivion for the 3rd week of a wafer.
The method involves taking two progestin pills (Stédiril ®) to 12 hours apart within 48 hours after intercourse (within 72 hours gives poorer results). For example, nightclub, meeting at midnight, the work of flesh at 3 o'clock, in the morning, sleep. Wake up at 10 o'clock, noon panic. What to do?
Take 2 pills as soon as possible and normodose renew the two pills 12 hours later. Point load hormone causes nausea and rules of deprivation that prevails in any fertilized egg.
More recently, taking a progestin (levonorgestrel) is based on the same principle. Found in pharmacies (OTC) boxes specially packaged with a tablet to take it very quickly (within 72 hours) and a 2nd to take 12 hours later. Efficiency is the same for fewer unpleasant side effects (less nausea).
Emergency Contraception First action: the installation of a copper IUD within five days after the report fertilizing. Delicate in the young girl and women not been pregnant, this method is rarely used. The second appeal is the morning-after pill, which there are two versions of hormones: progestin or progestin alone.
Warning! That contraception is opportunistic, not systematic: for your peace and it is best to consult his doctor. It remains the condom (well spent) to open access, low-cost and use impromptu.
