During a woman's menstrual cycle, there
are only about three days when her egg is available for fertilization. Sperm can survive
up to 72 hours (3 days) in the vagina and uterus, so if sexual intercourse occurs up to
three days before a woman is fertile, she can still potentially become pregnant. Thus,
there are about six days per month (3 days prior to fertility, and 3 days of fertility)
that a woman can conceive.
When tracking the days of the menstrual cycle, the first day of menstruation, or
bleeding, is called day 1 of that cycle. The cycle ends when the next period begins,
anywhere between day 17 and 35 (with most women it's around day 28). The egg may become
available for fertilization by sperm at anywhere from day 3 to day 14 of the cycle. Thus,
if a woman can identify those few days when she is fertile, she can prevent or enhance
conception.
As mentioned in The History Of Saliva Ferning,
saliva has been used to detect patterns in the body for years. Now with this
information and the power of understanding the hormonal cycles and patterns of woman, we
can use this to our advantage. One does not have to be a scientist to match up a few
simple patterns viewed through the eyepiece.
When a women is in an
infertile time and estrogen is low typically she would see a random pattern of scattered
dots. This marks these days as infertile. This is of course the safest time if
one does not wish to conceive and would account for somewhere about 22-24 total days,
before and after ovulation of course, in a "normal" 28 day cycle. |
