Implantation bleeding is associated with pregnancy signs, which usually occurs around six to twelve days following ovulation and fertilization. Some of the most common signs of implantation include implantation cramps, bleeding, a second temperature shift on the temperature curve and lowering of temperature at about 7 to 10 days after ovulation takes place. Bleeding does not always ensure pregnancy, and therefore, a positive pregnancy test can only confirm pregnancy with certainty.
When the fertilized egg gets attached to the uterine lining, it is called implantation. This occurs only when the egg is fertilized and travels through the fallopian tube and finally adheres to the lining of the uterus. Bleeding during implantation is one of several other pregnancy symptoms and happens during implantation. Health practitioners always recommend to go through a medical test to confirm implantation.
