Protective methods for red days

Use protection on red days to effectively prevent a pregnancy, or abstain from vaginal penetration. The risk of getting pregnant is significantly higher on these days as you are very likely to be fertile. What type of protection you choose to use on red days is up to you. But the relative effectiveness will depend on that method’s Pearl Index. We recommend the use of the male condom or to abstain from vaginal intercourse during red days, as these two are the easiest to use and most effective methods.

Perfect use is the number of pregnancies when the method has been used according to instruction. Typical use is the rate most people achieve, as perfect use can be hard to achieve for many of the methods - such as withdrawal. A number close to 0 is to be preferred.

Achieving correct use of withdrawal is very difficult, as sperm can often be laying in the vas deference and join the pre-ejaculation fluids during sex, causing a pregnancy despite the main ejaculation not entering the woman. Therefore, we do not recommend using withdrawal on red days.
