How many free period days do we get a month?I tried the ladytimer and period tracker application on my Android but they both different when it comes to my ovulation days... de free period days is wats most important to me

ANY computer based application is utterly worthless...

Women's cycles are not as consistent or reliable as celestial events.. and no computer app can make allowances for the LARGE variations between women.

If you want to know when you actually Ovulate... the ONLY way you are going to find out is Taking DAILY basal temp readings and maintaining a chart. YOU can put 100 women in a room whoes period is in synch... and most of them will not ovulate at the same time.. the variance is so great one person or another will be ovulating on almost every day of the month...

And there are no "safe" days.. many women are known to have gotten pregnant ON their period... and we have members that have gotten pregnant despite properly using multiple forms of birth control.
