WHY: Day 3 testing refers to the bloodwork and ultrasound evaluation performed on the third day of your menstrual cycle. This testing provides critical information regarding a woman’s reproductive functioning.

HOW: Day 3 is considered the "third day of menstrual bleeding." Full flow by 5pm is considered/counted as "Day 1." For example, a woman who starts her full flow on noon on a Monday, would count that Monday as Day 1, and have her Day 3 assessment on Wednesday morning.
