Sometimes a small amount of spotting or vaginal bleeding is one of the first symptoms of pregnancy. Known as implantation bleeding, it happens when the fertilised egg attaches to the lining of the uterus â about 10 to 14 days after fertilization.
It takes place during the menstrual cycle, and the process is called ovulation.   (Another name for the fertilized egg is a 'zygote')   Ovulation is not a fertilized eggâ¦. Ovulation is the release of an unfertilized egg. The fertilized egg implants about 6-8 days after ovulation.
