Implantation Bleeding and Menstruation

it lasted for 5 days. why i suspected it because the output is pink and watery with small amount of red blood. There is a two days cramp which is something new to me and small amount of blood clots. plus the menstruation came o 1 week earlier than expected

Implantation bleeding is usually just spots. Not flowing blood. It lasts a few days only usually before your period is due.
