Yes, decidual bleeding can occur after implantation bleeding. Implantation bleeding typically happens when a fertilized egg attaches to the uterine lining, usually around a week after conception. Decidual bleeding, on the other hand, can occur later in pregnancy, often due to hormonal changes or the shedding of the decidua (the uterine lining during pregnancy). While both types of bleeding can be normal, any unusual bleeding during pregnancy should be discussed with a healthcare provider.

This is called inplantation bleeding usually a week or two.
I would test just to be sure. You can have bleeding in early pregnancy.
