FCOG-1075

A 28-year-old woman presents for an antenatal visit in her first pregnancy. The pregnancy has been progressing normally thus far. Her routine mid-trimester ultrasound examination, performed at 18 weeks of gestation, shows that the placenta occupies the lower part of the uterus. It is noted that the placenta is reaching to within 1 cm of the internal cervical os. The patient is wondering what this means for her pregnancy and what needs to be done about it.
