Natural family planning
Combining all fertility indicators
NFP is most effective when all the fertility indicators are used together. This acts as a double check. In addition, many women are aware of other ovulation signs, such as changes in the breasts, skin, mood or sexual desire.
Are there any other ways?
Fertility devices work by monitoring changes in temperature, urine and saliva. In the UK the main device available to buy is Persona. This consists of a small handheld computerised monitor and a series of urine test sticks, which measure hormonal changes. Persona interprets these changes and predicts when a woman is fertile and infertile. If you use Persona according to the instructions, it is 94% effective.
A number of new and different devices will become available during the next few years as research improves, so well keep you up-to-date with these, as and when they come on to the market.
