What are the signs that implantation bleeding is abnormal?

While implantation bleeding is generally considered normal, there are certain signs that may indicate an abnormal or concerning situation:

Heavy bleeding: Implantation bleeding is typically light and resembles spotting or a brown discharge. If the bleeding becomes heavy or resembles a standard period, it could be a sign of a problem.

Severe cramping or pain: Mild cramping may occur during implantation bleeding, but severe cramping or pain could indicate potential hazards such as an ectopic pregnancy.

Prolonged bleeding: Implantation bleeding typically lasts for 1–3 days. If the bleeding persists for more than a few days, it may cause concern.

Clotting: Significant clotting is not common with implantation bleeding and could be a sign of an issue.
