If there is a serious reason to avoid pregnancy, a family planning progesterone blood draw can confirm ovulation has passed. In a 13-year study (632 cycles/105 women, including women with multiple children), there were zero reported pregnancies using the family planning progesterone blood draw.

After learning the Creighton Model, intercourse should be avoided to avoid pregnancy on the heavy and moderate days of the menstrual flow and the baby days as shown on this chart. The baby days represent an average of 5-6 days of mucus plus 3 days to account for post-peak ovulation.
