Could this possibly be implantation bleeding? 🤔

This happened yesterday, I was Anywhere from 7-9DPO. I only spotted like this yesterday, very light pink. I wore a pad overnight thinking it could possibly be my period coming on but there was no more on my pad this morning and I haven’t bled since. Could it possibly be implantation bleeding? If it was how long do I wait until I test? I’ve had no symptoms of pregnancy or anything though. But my cervix is high & soft and it’s usually low and hard before my period but I know cervical position isn’t really reliable

Thanks!
