What is implantation bleeding?

Implantation bleeding is often mistaken for spotting between periods. Typically implantation bleeding will happen somewhere between a week and a few days before your expected period.

Implantation bleeding will appear as darkish brown or pinkish in color. The blood can even be almost black due to the amount of time the blood travels in the body. The amount is typically sparse. If you are having bright blood or lots of it, it is likely not implantation bleeding.

Implantation bleeding is named as such because it is a result of a fertilized egg implanting in the uterine lining. The uterine wall is blood-rich environment. Implantation takes place roughly nine days after your body ovulates.

Sometimes a woman will experience cramping at the time of implantation. Other women do not report this experience.
Twenty to thirty percent of women will experience implantation bleeding. Not all women experience implantation bleeding. If you are trying to get pregnant, do not worry yourself watching for this small blood event. Many women get pregnant and never have any implantation bleeding whatsoever.

If you do see what you believe to be implantation bleeding, resist the temptation to run out and buy a pregnancy test. The test is simply not sophisticated enough to pick up on the hCG levels at the point of implantation bleeding and report a pregnancy. See here when to take a pregnancy test.
