Implantation?

I am currently 9dpo and I felt a rush of something(tmi) thought it could be my period coming early it's currently due the 17th or 18th but it was a lot of white creamy discharge and when I wiped I saw a light pink spot and then some tiny tiny spots of blood then it was gone. Has anyone else experienced this before and ended up being pregnant? I'm going to test Monday if I don't get my period in the morning. It usually shows as soon as I wake up like clock work. Any input is appreciated!
