The length of MSD increases by approximately how many millimeters per day?

Explanation:
Mean sac diameter grows at a steady pace in early pregnancy as the gestational sac enlarges before the embryo is large enough to measure reliably. The established teaching is that this growth is about 1 millimeter per day, which translates to roughly 7 millimeters per week. This consistent daily increment helps estimate gestational age when the embryo isn’t yet visible. While measurements can vary slightly with technique, 1 mm per day is the standard rate, making it the best answer.
