You may notice that the DontGetpreggy Guide I made was intended only for those women who had a regular monthly menstrual cycle. So one may ask how about those who have an irregular menstrual cycle? How will they or how can they prevent unintended pregnancies? Well, for those women with irregular monthly periods, there are some other form of contraceptives in order to avoid the consequences of having an unplanned pregnancy.

There are so many other contraception nowadays, which you can choose from and among them are IUD, pills, male condom, diaphragm, female condom, withdrawal and spermicides. But the effectiveness of all these rely much on how well the procedures are being consistently and correctly followed. You just have to seek the right one for you. You can choose a contraceptive that's used daily, weekly, monthly, once every three months, once every three years or even once a decade.

In the chart above, the rate of failure was significantly higher than those who followed the procedure with consistency and precisely. The chart also shows that IUD's appear to be one of the safest forms of protection against unintended pregnancy.
