In the fertility awareness methods overview I would like to draw your attention one more time to the methods that involve considering the changes a body of a woman undergoes during her menstrual cycles. These methods can help to learn when the woman is to ovulate and so can be applied to plan in-time sexual life for both avoiding pregnancy and getting pregnant.
There's a certain period within which a woman can be able to get pregnant (in case she's healthy and of a proper age, of course). The period lasts for about 5 days each month and she can get pregnant when ovulation actually happens. Fertility awareness methods overview provides us with information how to keep "safe" during these days in case you have sex and don't want to get a baby. So, the key question is to find out when ovulation occurs and take the recommended measures.
Really, it's not completely safe to have sexual intercourse without any condom or contraception even before this period starts because spermatozoids are able to live for three-five days and impregnate a woman when the period starts even if there's no sex during it. Many women don't really like this method because it takes a long time and requires preparation, as well as close monitoring of the body changes that is rather undertaking and even boring. Anyways it is the healthiest way, though to get the desired result you should apply all the methods together.
In its fertility awareness methods overview I'm going to mention four ways of natural birth control. A calendar tracking method concerns counting out the days that are considered to be the most fertile ones in the whole cycle, but it is possible to do only in case the cycle is regular. The fertile period starts 5 days before the ovulation comes. But our life is full of stresses that impact sexual life and the cycle as well, and you can never be sure your ovulation comes on the same day as it was the previous month. So, I wouldn't consider this method so that useful.
Also, a woman does not always ovulate right in the middle of her cycle. The best estimate is that ovulation occurs between 9 and 17 days before the next period. Therefore, use of the calendar method alone is not recommended as a method of birth control.
The basal body temperature method is based on taking your rectal temperature every morning still staying in bed. The thing is that normally your temperature in the second phase of the cycle (after ovulation) is higher. And according to this rise it's possible to determine if there ovulation occurred and when it actually occurs. But a wide range of factors can impact on it, and you should remember and mind this fact.
Cervical mucus method. The mucus produced by the cervix changes during the menstrual cycle and is hardly ever completely the same. That's why it has sense to monitor mucus texture and appearance for it will help you to determine if it's possible or not to get pregnant on every particular day of the cycle. To see the mucus's properties you should with your fingers washed clean get not deep into the vagina. You may feel that it's "dry", "damp", and "moist" in there. If the mucus is elastic, thin, and clear, you can say it's a period before and during ovulation.
Lactation amenorrhea method is the next one in the fertility awareness methods overview and it can be used in the first 6 months after having a baby. The method is good for health of both the mother and the baby and is based on not having periods while suckling and so she is not able to get pregnant again. A woman must start suckling right after the accouchement. The method is effective only if the lactation is complete. If a woman starts to wean or feed the baby with not only her milk but other products as well, the method gets less effective.
If you want to plan your life and have babies when you really want, the presented methods are to help you with it.
