If you had bleeding and cramping 4 days after sex but your period due for another week could it be implantation bleeding?

Implantation bleeding, which is light bleeding that occurs when a fertilized egg implants into the lining of the uterus, typically happens between 6-12 days after ovulation and lasts for a few days. Since you are experiencing bleeding and cramping 4 days after sex and your period is due in another week, it is unlikely to be implantation bleeding. It is more likely to be spotting, which is common during the menstrual cycle, or a sign of an underlying condition such as infection or hormonal imbalance. If the bleeding and cramping persist or become heavy, it is important to see a doctor to determine the cause and receive appropriate treatment.
