Implantation Bleeding: What It Is and What to Expect

Implantation bleeding is light vaginal bleeding occurring when a fertilized egg attaches to the uterine wall, typically 10–14 days after conception. It lasts a few days, with pink or brown blood often only noticeable when wiping.

It differs from a menstrual period: periods are heavier, monthly, due to uterine lining shedding. Implantation bleeding is lighter and shorter.

If unsure whether bleeding is implantation or a period, consult your doctor.
