If your cervical mucus starts breaking down after ovulation is that a good sign you are not pregnant?

The breakdown of cervical mucus after ovulation is not necessarily a good sign that you are not pregnant. Cervical mucus changes are a normal part of the menstrual cycle, and they can vary from person to person. Some women experience a decrease in cervical mucus after ovulation, while others may experience an increase. Changes in cervical mucus alone are not a reliable indicator of pregnancy or the absence of pregnancy. To determine if you are pregnant, it is best to take a pregnancy test or consult with a healthcare professional.
