Ovulation bleeding is a very common phenomenon, usually starting on the 14th day of the menstrual cycle and lasting for about 2-3 days. While this phenomenon itself does not affect conception, if you have sex during ovulation bleeding, the likelihood of pregnancy is reduced.

While ovulation bleeding itself won't affect pregnancy, it's best to talk to your doctor if you have concerns or symptoms. A doctor can evaluate your health and provide necessary treatment recommendations.

If you are planning to become pregnant, it is best to avoid sex as much as possible during bleeding until the bleeding stops and wait at least 2-3 days before acting again. In addition, you should follow your doctor's advice during bleeding to ensure good health.
