6. Avoiding Pregnancy with Natural Family Planning
In natural family planning, there are several ways of determining the end of
pre-ovulation fertility and the beginning of post-ovulation infertility.
Professionals teaching natural family planning claim most unplanned
pregnancies occur during pre-ovulation infertility. This booklet does not
include guidelines for natural family planning, since it is beyond the scope of
this booklet.
Your Ovulation digital thermometer only helps you determine when ovulation
has occurred. Calculating infertile periods involves other bodily signs in
addition to temperature change and requires professional guidance when
avoidance of pregnancy is your objective.
