Whether ovulation occurs on the day of ovulation bleeding is a controversial issue. While most people think of ovulation bleeding as the release of an egg on the same day or the next day, some research suggests that an egg may also be released a few days before or after the bleeding.

Breakthrough bleeding is not really bleeding; it only lasts for a few minutes or hours and then stops naturally. Breakthrough bleeding usually doesn't have a big impact on your health, but it may increase your risk of infection.

For women trying to get pregnant, understanding the timing of ovulation bleeding and egg release can help them better plan their pregnancy. If a woman wants to get pregnant during ovulation bleeding, she should try to do so within a few days of the bleeding ending to increase her chances of fertilization.

In short, whether an egg can be released on the day of ovulation bleeding is a complex issue, and more research is needed to understand this issue. However, if a woman wants to get pregnant during ovulation bleeding, she should try to do so within a few days of the bleeding ending to increase her chances of fertilization.
