Pregnancy Predictor

WebMD and other sites warn not to use their predictors to prevent pregnancy. All sites of ovulation prediction that I found are geared towards people who want to become pregnant.

You can still use the predictors to determine when you're most likely not get pregnant. Use the reverse? It seems a bit obvious answer for me. : S
It is much easier to go on the pill, but I would say.

A predictor ovualtion is only to tell you when you are ovulating - if you use this information to get pregnant or not. The only 100% to prevent pregnancy is not to have sex at all. Otherwise, I recommend you use a dual approach - condom and diaphragm or something like that. There is always a chance of getting pregnant even with the "pull and pray". Before a man ejaculates, there may be semen on the tip, which puts you at risk of becoming pregnant. It is not true that you can get pregnant while ovulating. I got pregnant while on my period - twins, one was in my tube and the other in the womb.
