Medically reviewed by Debra Sullivan, Ph. The process goes like this: Your body releases a mature egg. This is ovulation. Sperm — either already in your body since the little guys can survive up to 5 to 6 days in the uterus or just making their grand entrance in the hours before ovulation — travel up the Fallopian tubes to meet the egg.

An egg is fertilized by a sperm in one of the two fallopian tubes. These connect the uterus with the ovaries, which sit to either side. The fertilized egg is called a zygote, and it travels down the tube toward the uterus. As it moves, it divides and grows, becoming a multicellular structure called a blastocyst.
The first stage of implantation occurs when the blastocyst attaches to the lining of the uterus, a mucous membrane called the endometrium. The blastocyst then buries itself in the uterine wall. Implantation is a complex process with a brief window — it happens about 6—10 days after ovulation. One factor influencing the timing is that the endometrium changes, thickening and shedding, throughout the menstrual cycle.
It is only receptive to a blastocyst for a few days in each cycle. Even if the timing is right, implantation may not happen.
According to researchers , a lack of implantation is a common cause of early pregnancy loss. Implantation bleeding is spotting or light bleeding that takes place about 1—2 weeks after fertilization. It is usually short-lived and lighter than a normal period. The blood is often paler than menstrual blood or can be a rusty brown. There has been little research about implantation cramping, but it may affect the lower abdomen or back and feel like:. Early pregnancy can cause additional symptoms, which may start a short time after implantation and continue for the first trimester and sometimes beyond.
