and maintainer of:
I have just released DateTime::Pregnancy 0.01 to CPAN.
I actually need some more test data. So if you or somebody in your family is pregnant or have been. I would be interested very in a few parameters from you, especially if you have an average period cycle length, which differs from 28 days.
All I need is the: average period cycle length and the date of the first day of the last period.
