How often should a healthy pregnant woman visit her healthcare provider during the first trimester?

During the first trimester of pregnancy, a healthy woman typically visits her healthcare provider every four weeks. These visits are crucial for monitoring the health of both the mother and the developing fetus while also providing an opportunity for the woman to ask questions and address any concerns.

Every four weeks allows sufficient time for healthcare providers to conduct necessary assessments, such as checking vital signs, monitoring weight gain, and scheduling necessary screenings and lab tests. This schedule follows the recommended guidelines for antepartum care, as healthcare providers aim for an optimal balance in frequency that ensures both continual support and the efficient use of medical resources.

The other options listed would imply a more frequent visit schedule that is not standard for healthy women during this stage. For example, visiting every two weeks or every other week would be more appropriate for those with complications or high-risk pregnancies, while monthly visits would not align with the recommended guidelines for the early stages of pregnancy.
