Can Ovulation Occur at Any Time During the Cycle?

Q: Can ovulation occur at any time during the cycle?

A: The exact day of ovulation can vary from one cycle to the next cycle. Once ovulation occurs, the hormone progesterone is produced by the corpus luteum in the ovary, suppressing the release of all other eggs until the following cycle. If ovulation occurs more than once, it usually happens within 12-24 hours of each other. Once a woman ovulates, it is virtually impossible for her to ovulate again until the following cycle.
