The journey of pregnancy is filled with excitement, anticipation, and a myriad of questions. One common inquiry is, “How many weeks pregnant am I?” The How Many Weeks Pregnancy Calculator is a valuable tool that provides expectant mothers and parents with an accurate estimate of the pregnancy’s duration. This calculator takes into account the date of the last menstrual period (LMP) to offer a reliable and straightforward answer.
