Question 24

A clinician is tracking the menstrual cycle of a patient who has a regular $33$ -day cycle (where day $33$ is the final day of the cycle).

Based on clinical data:

Ovulation occurs $14$ days before the end of the menstrual cycle.
Sperm cells can survive inside the female reproductive tract for up to $5$ days.
The egg cell (oocyte) remains viable for $3$ days after ovulation has occurred.

Calculate the range of days of her cycle during which sexual intercourse could result in fertilisation.

Give your answer in the form: From day $A\text{A}$ to day $B\text{B}$
