Cervical length after 24 weeks in pregnancy
is not a good predictor of preterm delivery, it is used primarily in the first and second trimester. In the US, it is NOT standard of care to perform a cerclage in the third trimester, and an cause rupture of membranes
, infection, and oher dangerous complications. In addition, a cervical length of 2.5 cm or less is usually the cut-off. Also the cervix can look short on an ultrasound
if they happened to check it while you were having a contraction, and so, if checked again, it can look normal. Right not you have a 4.8 cm cervix which is totally normal. If you have no contractions and no other risk for preterm delivery (like a positive fetal fibronectin
test, twins, previous preterm delivery) , there is no reason you should need to be on bedrest
or be treated differently from any normal pregnancy.
