Here is an explanation I found describing how to calculate failure rates:
Contraceptive effectiveness is usually reported as a percentage. These different effective numbers represent success in âwomen years.â So if a form of birth control is 98 percent effective, that means that, on average, 98 out of 100 women using it for one year will not get pregnant. Occasionally, contraceptive effectiveness is reported in terms of âfailure rates.â So in the above content, the same form of birth control would have a 2 percent failure rate, meaning that 2 out of 100 women using this form of birth control would get pregnant in the period of one year. You also often see two numbers reported for each form of birth control, ideal and typical. Ideal represents the level of effectiveness if used perfectly every time; typical rates take into account human failure. Hereâs a neat trick: you can compute the effectiveness of combining two forms of birth control by multiplying the numbers. So for example, if you combine a condom (12 percent typical failure rate) with spermicidal foam (21 percent typical failure rate), the failure rate plummets to 2.5 percent.
I'm hoping it can't get you pregnant,I just had sex for the first time ever and used the pull out method and now I couldn't be anymore scared. . .I'm stupid I know but I've been praying every night that nothing happens. I know next time to be smarter.

It is true, you can get pregnant from pre- cum. Pre-cum act as a cleanser when a man becomes erect. Pre-cum flushes out the acids left by urine, that can otherwise kill sperm. Although pre-cum does NOT consist if live sperm, if a man became erect directly after ejaculating, and did not urinate, the pre- cum can carry the left over live sperm to the woman's fallopain tubes. Urine will kill and flush out live sperm if a man urinated after ejaculating. However as I stated before if a man does nit urinate, and live sperm are still present in his urethra, then pre-cum can carry sperm through the woman's urethra. Although the chances of a woman becoming pregnant from pre-cum are not very probable, that does NOT mean that it is impossible. It IS very possible!!
I don't think you are pregnant. Sometimes a women get the " prego" symptoms when their period approaches. If you do some research about it you will find that it is very common for a woman to experience soarness of the breast and aches on areas of the body. As far as cravings and mood swings and irregular periods , those are common also. Sometimes we think too much into things and we start to "will" symptoms into effect. However it is always better to be safe than sorry, so if you are really worried go get a pregnancy test from your local drugstore.
