| Re: woman fertil and non fertil time?
Actually, a woman is fertile when she ovulates, which is approximately 14 days BEFORE her next period - that time frame is very consistant, while the amount of time from her last period to ovulation is less so.
However, since sperm can live a number of days, her 'fertile' time also includes the days before her expected ovulation and a few days after, for safety.
