Can pregnancy spotting appear when period usually comes that's why girls usually confuse with period?

Yes, pregnancy spotting can occur around the time when a girl expects her period, leading to confusion. This light bleeding, often referred to as implantation bleeding, typically happens when a fertilized egg attaches to the uterine lining. Unlike a regular period, pregnancy spotting is usually lighter in color and flow. As a result, many may mistake it for an early menstrual period.
