Assisted: Many women who are planning an unassisted birth choose to have professional prenatal care as part of their birth preparation. This may include regular prenatal visits with a doctor or monitoring by a midwife. Seeking the assistance of a doctor or midwife may allow for discovering risk factors that might make an unassisted birth inadvisable, such as placenta praevia. Professional prenatal care may also help identify risk factors that could be managed so that the unassisted birth can continue as planned. Rather than keep to a traditional prenatal care schedule, some women may also selectively choose prenatal care.
