Explanation

"Last menstrual period" refers to the most recent time a woman experienced her monthly bleeding, which is part of her menstrual cycle. This is often used by doctors to help calculate the due date if a woman is pregnant. The date is used as a starting point because it's usually the last time when a woman was definitely not pregnant.
