Types of hormonal contraceptives

The first is the aforementioned combined OK.In their composition, there is always an analogue of female hormones. Their principle of operation is monophasic. That is, if to express more simply, under the influence of these tablets the level of hormones in the female body does not change. There are also three-phase ones. How does this type of birth control pills work? A little bit different. If the girl takes them, then the combination of her hormones changes throughout the menstrual cycle.

Both one and the other OK are divided into groups. Everything depends on the characteristics of the woman's body. There are micro-dosed tablets - ideal for nulliparous girls and for those who are just starting to take OK.The body easily absorbs these drugs, and they, in turn, do not do him any harm.

There are also low-dose. Usually they are given birth to those giving birth. But still this group of OK is suitable for girls who did not come for some reason tablets of the first type.

In general, speaking about how the contraceptive pills work, you can note one thing - they have the principle of work alone. They slow down the process of ovulation, and because of this the egg is not fertilized. In addition, they affect the mucous membrane of the uterus. In other words, the mucus that is in the uterine canal condenses. And so much so that the spermatozoa elementary can not get into the fallopian tube. What to say about fertilization! And this shell is getting thinner. This means that even if the spermatozoon penetrates inward, the embryo will not be able to gain a foothold on the cavity.

Break

Much has been said about how and from which day the birth control pills. Finally a few words about the breaks, which must be done between the methods. Usually accepted OK for 21 days. Then, for seven days, a break is made until the next pack. This week just happens menstruation. But in the case of the aforementioned "Jess", for example, everything is a little different. There are 24 regular tablets and 4 placebo in the package. And do not need to take breaks - instead of these four tablets go. After they are finished, we need to start a new pack.
