Fetal Implantation Symptoms

Implantation occurs when a fertilized egg attaches itself to the wall of the uterus. A fertilized egg usually remains in the fallopian tube for three days before traveling to the uterus and implanting.

Time Frame

Implantation usually occurs about six to 12 days after ovulation.

Common Symptoms

Very light bleeding or spotting--known as "implantation bleeding"--is one of the most common signs of implantation, experienced by about one-third of women. Blood is usually pinkish or brownish; it may be light enough to escape notice.

Other Signs

Other symptoms of implantation are minor cramping, a rise in basal body temperature or a temperature dip lasting one day.

Considerations

Symptoms of implantation are usually subtle and not experienced by all women. Their presence or absence is an unreliable predictor of pregnancy.

Fun Fact

Just before implantation, the fertilized egg is called a blastocyst; it becomes an embryo after implantation.
