Should I Have More Tests?
To determine if bed rest -- or something else -- is best for you and baby, ask your doctor the following questions. Together you can devise a plan.
Simply having contractions does not mean you're in preterm labor. They must be accompanied by cervical change (dilation or effacement). If you're having contractions, ask for an ultrasound to determine whether the cervix has shortened or thinned out. Another valuable test looks for the presence of fetal fibronectin, a protein that helps the fetal sac attach to the uterine lining. While a negative test is "very good at suggesting you're not going to deliver," a positive test is less definitive, says Dr. Riley. Based on the results of these tests, your doctor may lean toward holding off on bed rest.
