What Is Implantation Bleeding?
Implantation bleeding is an early sign of pregnancy that occurs when a 6 to 12-day-old fertilized egg attaches to the inner lining of the uterus, resulting in light vaginal bleeding or spotting. It is a normal experience that typically happens near the time of a woman’s next expected menstrual period.
What Is a Menstrual Period?
A menstrual period is when blood and tissue from the uterus is expelled through the vagina. In most women, this happens monthly.
A menstrual cycle is how the body prepares for the possibility of a pregnancy. Hormones in the body cause the eggs in the ovaries to mature and the lining of the uterus thickens in case the egg is fertilized by sperm. The lining of the uterus is made of blood and tissue. If pregnancy does not occur, the body sheds this lining, which flows out of the body through the vagina during a monthly menstrual period.
Periods typically start in girls during puberty, around the ages of 12 to 14, but some girls may get them earlier or later. Menopause – when periods stop – usually occurs in women between the ages of 45 and 55 years old.
