* [**Conception Date**](#steps-to-calculate-using-conception-date)
* [**Estimated Due Date**](#steps-to-calculate-using-due-date)

Each method gives a comprehensive view of the patient’s pregnancy progress, including trimester timelines. This screen is accessible only for female patient records. For male patient records, the screen is disabled.
