Was it implantation bleeding or period if you bled shorter and lighter two days before period is actually due ovulating eleven days and having intercourse seventeen days prior?
It is more likely to be implantation bleeding if you experienced shorter and lighter bleeding two days before your period was due, along with ovulating around 11 days prior and having intercourse 17 days before. Implantation bleeding can occur when a fertilized egg implants in the uterine lining, typically around 6-12 days after ovulation. If you suspect pregnancy, consider taking a pregnancy test to confirm.
