Ovulation refers to the time when an egg is released from a woman's body, usually on the 14th day before the next menstrual period. This is a very important period for many women because during this time their eggs may mature and be released, giving them a chance to have offspring.

While women who get their period on the 23rd may not have children during their true ovulation period, that doesn't mean they can't enjoy pregnancy. In fact, many women can take steps during the period of ovulation to increase their chances of getting pregnant.

First, women can have sexual intercourse during ovulation, which can increase the chance of pregnancy. Second, women can take steps to protect their bodies and avoid pregnancy. For example, they can take emergency contraceptive pills or take other steps to avoid pregnancy.

To sum up, for women who have their period on the 23rd, their ovulation period may not be the real ovulation period, but this does not mean that they cannot enjoy pregnancy. Therefore, women should understand their bodies and take steps to protect themselves when necessary.
