Ovulation or implantation

Hey ladies. The end of august to September 1st ive Been having spotting it was the end of My ovulation week. The spotting wasn't back to back but I've experienced spotting 3 times that week and I'm not sure why . It's like pinkish. And the second time it was brownish pinkish. I'm not sure what's going on. Could this be ovulation bleeding or implantation bleeding? My period is supposed to start in 6 days. I've also been having other symptoms. Please comment or answer poll
