What Is Implantation?
Implantation is when a fertilized egg attaches to the lining of the uterus. This is a crucial step in early pregnancy. It's when the embryo begins to receive nutrients and the body starts producing hCG, the hormone detected by pregnancy tests.
When Does Implantation Happen?
After ovulation and fertilization, the embryo travels through the fallopian tube for several days. Implantation typically occurs between 6-12 days past ovulation (DPO), with the most common window being 8-10 DPO. The entire process takes about 1-3 days to complete.
Signs of Implantation
- Light spotting: Some women notice very light pink or brown spotting lasting 1-2 days.
- Mild cramping: Lighter than period cramps, often felt in the lower abdomen.
- Breast tenderness: Hormonal changes may cause early breast sensitivity.
Many women experience no noticeable symptoms at all. The absence of symptoms does not mean implantation hasn't occurred.
