does your cervix close when pregnant
Cervix in Early Pregnancy. The lower end of the uterus is a narrow, tubular-shaped structure that is called the cervix. It extends into your vagina and fills with secretions during pregnancy to form a protective barrier called the mucus plug. When you're pregnant, your cervix is in a firm, long and closed position until the third trimester.
The cervix is the opening to the womb. Itâs located between the vagina and the uterus and plays a crucial role in pregnancy and labor. During pregnancy, it remains closed and the opening is blocked with a mucus plug.
