Missed Period
A missed menstrual period is usually the first sign of pregnancy for many women. Sometimes a small amount of implantation bleeding occurs and can be mistaken as a period and pregnancy is not suspected or confirmed until a second period is missed.
It is unusual for pregnant women to continue menstrual periods though it has been known to happen. For mothers who already have given birth, leaking breast milk may signal subsequent conception.
