Frequently Asked Questions
When does implantation happen?
Implantation typically occurs 6–12 days after ovulation, most commonly around day 9. This is when the embryo burrows into the uterine lining.
What are signs of implantation?
Some experience light spotting (implantation bleeding), mild cramping, or breast tenderness. Many women notice no symptoms at all.
When can I take a pregnancy test after implantation?
HCG levels are detectable about 10–14 days after ovulation. Testing too early may give a false negative.
