Thick cervix early pregnancy sign or period sign?

A thick cervix can be an early sign of pregnancy, but it is not a definitive sign. During pregnancy, the cervix undergoes changes and may become thicker and softer due to increased blood flow and hormonal changes. However, cervical thickness can also vary during the menstrual cycle. A thick cervix may also be a sign of other conditions, such as an infection or polyp. Therefore, it is important to consult with a healthcare professional for an accurate evaluation and diagnosis.
