Whether you are a new mom or a well seasoned one, the last thing that you want to hear at any stage in your pregnancy is the word “negative.” It immediately fills your head with the worst possible ideas, causing you undue stress. Late in pregnancy, a midwife or doctor may start to check your cervix to see about effacement, dilation and station (although many no longer do, due to the inaccuracy of these measurements in a normal pregnancy). If you hear things like “1 centimeter, 25%, -2” and that negative number makes you worry, don’t. First, check out this guide on effacement, dilation and station so that you are better informed at your next appointment.
