So you're telling me that I could have unlimited unprotected sex with my partner for three weeks out of every month (assuming we had perfect fertility information about those three weeks) and there would be 0 chance that they would get pregnant...?
- kbsletten 9y agoYes. The problem is nobody has "perfect fertility information". Little flukes in exact timing could change the "safe" days significantly. There's actually a whole bunch of info for couples wanting to do this with multiple ways to track fertility with more or less invasive options.
- chillacy 9y agoYes, this is called the Rhythm Method / natural family planning: http://www.everydayhealth.com/sexual-health/rhythm-method.aspx http://www.everydayhealth.com/sexual-health/rhythm-method.as... Of course the tricky part is having perfect fertility information
- dozzie 9y agoThis method is also called "Vatican roulette".
- true_religion 9y agoVatican roulette has worked for me for over ten years... Or I'm infertile. It's kind of a toss up, but anecdotally I wouldn't rely on it if you wanted frequent sex. All contraception is a probability issue but there's a huge difference between 99% and 80%.
