  [BIOLOGY, DOS]
 <After reviewing the MENSTRUA program, I speculate there is some
information that is needed. I input data on my menstrual cycle,
which the program would not allow because it hypothesized that my
cycle was too long. The fact is, my menstrual cycle  is sometimes
nine days long. I think the program is based on the average cycle
of a woman. Every woman is different, they may menstruate for three
days one month and nine another which would make their ovulation
different than the above data. The calendar method was very good in
showing a person when she starts her cycle, when it ends, the
potential fertile phase, and the potential fertile period. The
MENSTRUA program reveals some interesting information and good
prediction for a good percentage of woman. It is very user friendly
and takes little time to get familiar with. Overall
 it is a good program. (REVIEW 2: RATING = 8)>
