13 DPO negative pregnancy test but had implantation bleeding on 11 DPO

Hey friends! I got a negative pregnancy test today at 13 DPO, but I experienced possible implantation bleeding on 11 DPO. Is it still too early to test? I am only struggling with this because my period is due tomorrow so I feel like I should be seeing a positive pregnancy test by now, but since my implantation happened so late, maybe I should wait as well? Just curious if anyone else who has had a successful pregnancy has experienced this! Thank you!
