Bloodays (also known as AiS Conception & Contraception Calendar) is a health program created so that women can calculate which are the days of the month when they are most likely to ovulate, to know the most likely moment to get pregnant.
Bloodays not only calculates the ovulating days, it also calculates the approximate time of your next menstruation, and whether the conceived embryo is boy or girl. There is also the information that shows you when there is no chance of conceiving.
The program lets you print out a very intuitive calendar that gives detailed information on all this data. Bloodays will become an essential tool for all those planning their sex lives.
