Natural methods
In natural family planning, a woman learns how to record fertility signals, such as periods, body temperature and changes in cervical mucus, to identify when she is most and least likely to get pregnant.
She can then avoid having sex or use other contraception methods when it's more likely she will get pregnant.
Natural family planning offers no protection against sexually transmitted infections.
It can take three to six menstrual cycles to learn these methods and it requires daily monitoring of fertility signals. This method lasts as long as you use it for.
