[2] This cerclage is usually placed between 16 weeks and 18 weeks of pregnancy.

Prior to effacement, the cervix is like a long bottleneck, usually about four centimeters in length. Throughout pregnancy, the cervix is tightly closed and protected by a plug of mucus. Effacement is accompanied by cervical dilation. When the cervix effaces, the mucus plug is loosened and passes out of the vagina.
Cervical pessary is a medical device used to treat an incompetent (or insufficient) cervix (cervix starts to shorten and open too early). Early in the pregnancy a round silicone pessary is placed at the opening to the cervix to close it, and then it's removed later in the pregnancy when the risk of a preterm birth has passed.
Sex positions for pregnant women.
