Could spotting 3 days after sex mean you are pregnant?

Spotting 3 days after sex does not necessarily mean you are pregnant, as there are many other possible causes of spotting. Implantation bleeding, which occurs when the fertilized egg implants in the uterine wall, can happen anywhere from 6 to 12 days after ovulation, and typically lasts for only a few days. However, it is also possible to experience spotting due to other factors such as hormonal imbalances or irritation of the cervix, which may be related to the sexual activity. If you are concerned about the possibility of pregnancy, it is best to take a pregnancy test to confirm.
