Implantation typically occurs 6-12 days after ovulation, with days 8-10 being most common. After fertilization, the embryo travels through the fallopian tube and implants in the uterine lining.
Common symptoms include: light cramping, spotting or light bleeding (pink/brown), breast tenderness, mood changes, and fatigue. Many women have no noticeable symptoms at all.
Implantation bleeding is light spotting that occurs when the embryo attaches to the uterine wall. It's usually pink or brown, very light, and lasts 1-3 days. Not all women experience it.
Home pregnancy tests detect hCG, which starts rising after implantation. Most tests are accurate from the day of your missed period. For early testing, wait at least 10-12 days after ovulation.
DPO refers to how many days have passed since ovulation. Implantation typically occurs around 6-12 DPO. Many women track DPO to understand their fertility window and early pregnancy signs.
Yes, not all fertilized eggs implant successfully. Up to 50% of fertilized eggs may not implant. Factors include embryo quality, uterine lining condition, and timing. This is often called a chemical pregnancy.
