The term “implantation bleeding” means that the fertilized egg will shed a small amount of endometrial lining when it is implanted in the uterine cavity, which will cause spotting and bleeding from the vagina. This is because ovulation usually occurs about 14 days before the next menstrual period, and the fertilized egg comes to bed about 7 days after ovulation, so there will be a small amount of vaginal bleeding around 7:00 pm after ovulation. As long as the bleeding clears up naturally and the embryo grows and develops normally, no other treatment is needed.
