The first poster is playing with disaster. Fertility calculation (any method) is difficult, unreliable, and if you are using it as the only method of birth control, sooner or later you will end up pregnant. Fertility periods can change and be affected by many things. Use BC if you don’t want to become pregnant. To do anything else will eventually end in a baby. Guaranteed!

I used to have irregular cycles and we were planning for baby, so I wanted to know my fertility period. On fertilityfriend.com, you have to enter BBT(basal body temperature). If your cycles are irregular, after first month, it will exactly tell you when you are ovulating and when can you get your next periods. It really worked for me. Hope this helps.
Infertility is the inability to get pregnant. There are a wide range of factors that cause infertility, which may prevent couples from conceiving. One-third of problems can be attributed to the woman, one-third to the man and the remaining one-third are attributed to both. In women, ovulation disorders can prevent the ovaries from releasing a healthy egg.
In men, problems with abnormal sperm production or function can cause infertility.
In some case, both the man and women may have specific infertility problems that cause them not to get pregnant.
