ImplantationWhether you are trying to get pregnant or potentially experiencing an unplanned pregnancy, there is one sign that may have you puzzled. Light, spotty or short bleeding may be a sign of implantation. This is confusing for some women because this light bleeding is often around the time a period is due.

What is implantation?

Are you wondering what is implantation? Implantation refers to the attachment of the fertilized egg to the uterine wall. Once the egg is fertilized the next step to determine if you have a pregnancy or not is implantation. The blastocyst, fertilized egg, travels down the fallopian tube and into the uterus looking to find a home in the uterine wall looking. Implantation normally takes place some time between 6 to 12 days following conception, usually occurring on day 9.

What is the implantation window?

The implantation window refers to the time frame where the endometrium is ready for implantation to occur. This period is approximately 4 days long. This 4 day period usually occurs within the 6 to 12 days post ovulation. Based on typical average cycles, this is normally between the 20th and 26th day of your cycle.

During this phase, the endometrium cells change into a state which allows the absorption of the uterine fluid. This helps the blastocyst (fertilized egg) get closer to the endometrium and supports mobilization.

Implantation Bleeding

It is quite possible that you may notice implantation because of light or spotty bleeding. When the blastocyst implants in the uterine wall, this sometimes creates bleeding in the process. However, don’t be alarmed if you don’t. Many women do not see any implantation bleeding. This bleeding is often considered the first sign or symptom of pregnancy.
