Pregnant women are at risk of giving birth too early when their cervix begin to efface (shorten) and dilate (open). Different treatments have been tried to prevent a late miscarriage or preterm birth. A common treatment is cervical cerclage or stitch when a suture is stitched around the opening of the cervix around 12–14 weeks into the pregnancy.[1] A cervical pessary is being studied as an alternative to cervical cerclage since there are fewer potential complications.[2] More medical studies are needed to decide whether a cervical pessary is equal to or the best treatment.[2][3]
