To not get pregnant when you are not ready it is possible to use a wide range of means that make having sex relatively safe. The Fertility awareness methods review list includes taking pills according to a specially developed schedule, and they seem rather reliable. But you can never be sure that they are harmless to your organism.
The other way for being safe is to use male and female condoms, diaphragms, sponges, cervical caps and so on. We can neither say they are the best way out, nor deny their being rather helpful, but doctors believe that it is better to use them if your sex is not on a regular basis or (it concerns condoms) you're not sure that your partner has no sexually transmitted diseases.
Some people take radical steps and decide to be operated on: it's called sterilization and can be performed both on women and men. The surgeon methods provide constant sterilization and there are usually no way back. But these methods are surely for those people who for some reason are determined not to have offspring at all, either because they already have some, or because of some disease or just their bare will.
Because 99.9 percent of red blooded males rely on the tried and true "stick the weenie-in-the-hole" method for getting their significant others pregnant, this means that they have to start thinking with the head on their shoulders and not the one in their pants.
In case you have a permanent sexual partner and prefer just to wait with having a baby, there is a way presented in the fertility awareness methods review as the most common and the most helpful one. It's a calendar tracking method that is based on counting out the fertile period (the time when the probability of getting pregnant is very high).
To find out when this period starts you should subtract 18 from the shortest cycle and to count out its end just subtract 11 from the longest cycle within the last 6-12 months. On average the period of continence equals 16 days - from the 5th till the 20th day of the cycle. The method's effectiveness is not so that big - 14-47 pregnant women from 100.
The basal body temperature method is based on measuring temperature every morning in bed. It takes 5-6 minutes and taken into the rectum via the anus. After 3 days of temperature being more than 37 degrees Centigrade you can have sex and be sure you'll not get pregnant. The efficiency of the method is rather big: 0.3-6.6 pregnant women from100.
All in all it's always up to the woman or to the couple to decide which way of the ones listed in the fertility awareness methods review is the best one for every individual case, but of course, the last one is believed to be far more natural than any other.
And the other thing you should always mind that natural birth control methods are used not only to prevent from getting pregnant but also to count out which date is the most appropriate one for conception. All the chemical means can cause changes in your organism that can even lead to sterility, but the last two ones will always help you to be the ones who decide whether to have a kid or not. But I wouldn't advise you to rely on any of the on full because they can't guarantee 100% effectiveness. Besides, contraception is a very individual thing, and any fertility awareness methods review can only provide general information. So, you always should discuss everything with a qualified doctor.
