This can be a "how to" thread as well as a place share stories, ask questions etc.
My husband and I have been using the nfp method of birth control for almost a year now and have not gotten pregnant.
It is very easy to do, it is free, it only takes two minutes a day, and it is an excellent way to strengthen your relationship (divorce rate among average married couples is more than 50%, divorce rate among couples who use nfp less than 4%). It is also as effective as birth control pills and more effective than condoms.
The way it works: your body gives three tell-tale signs every month that you are about to ovulate, are ovulating and/or have ovulated. This is true even if your cycle is irregular; it is still possible to know when you have ovulated.
Nfp is for couples who both want to get pregnant or do not want to get pregnant, by teaching them what the symptoms are and how to check them, so you can know if you are ovulating/fertile or not.
Before we get into the details of the symptoms, let me say that there are books on this method that will be able to help you with a lot more information that I will give you. The one I read was called the art of natural family planning. It is the only method that suggests you use all three symptoms to tell if you are fertile or not. Other methods recommend just two or one. But with using three, you have two cross-checks to make sure you know when you are fertile.
Basically: our bodies are designed to go through a monthly cycle. When one thing occurs it causes a reaction which leads to another. For example, a certain hormone will end your period. In about a week (it's different for everyone and unwise to try to count the days) you will ovulate. (we'll look at how to tell those in the next post). When you ovulate, an ovum, or egg, is relased from your ovaries. The follicle in your ovary that released the ovum then turns into a hormone which signals to your brain to build up the lining of your uterus (why you begin to feel bloated, crampy, etc.) if the ovum or egg is not fertalized it does not attach to the lining of your uterus which causes another hormone reaction that sheds the lining--your period. Birth control pills force this reaction so that, even if the egg is fertilzed, your lining will shed anyway.
Cycles range any where from 21-45 days. Even with such a broad range it is possible to tell when you are ovulating, and be confident that you are fertile or not fertile.
Once you ovulate, it is impossible to get pregnant because there is nothing to fertilze. You typically will have about two weeks (possibly shorter or longer, depending on the length of your cycle) when you can have sex without fear of getting pregnant.
If you do want to get pregnant, you simply have sex during the days you are fertile.
You cycle begins on the first day of your period. The first day you have your period is considered "day 1" of your cycle. Your cycle lasts until you have your period again. The last day before you next period is considered the last day of your cycle and the first day of your next period is the first day of your next cycle.
You can also have sex during the first 2-3 days of your cycle (2 if your cycle is short, 3 if 28 days or longer) and not get pregnant, if you are comfortable having intercourse during your period. In over 40 years of studies and hundreds of thousands of women charting their cycles for months and months and months, only one pregnancy has resulted from intercourse on the fourth day of a period. It is extremely unlikely, but it has happened, so it is recommended that you do not have sex any later than the third day of your cycle.
After your period ends you will have a few days before you ovulate. The longer your cycle is, the more days you will have between the end of your period and the day you ovulate. You can still get pregnant if you have sex between the end of your period and the day you ovulate, i'll explain that in the next post about symptoms of ovulation. You can't count the days because it varies month to month depending on diet, exercise, stress, sickness, etc., and it is different for every person.
We'll get into the signs of ovulation in the next post.
After you ovulate, and you are *sure* that you have ovulated, you can have sex as many times as you want until your next cycle begins (the first day of your next period) and you will not get pregnant. Some women have been known to ovulate twice in one cycle, but this is very uncommon. However, it is good to check your symptoms every day (it only takes about two minutes of your entire day) to be sure, as you would be able to tell through the symptoms if you have ovulated a second time. But like I said , *this is very uncommon*
