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.
If conception occurred, implantation (when the fertilized egg attaches to the uterine wall) typically happens seven to ten days after ovulation, but it can happen a few days earlier or later as well.ome possible signs of implantation or successful conception are: 1  light spotting that happens for just a brief period of time around seven to ten days past ovulation. 2  a second thermal shift that occurs around seven to ten days past ovulation.
