Implantation bleeding question

So we are trying for our 2nd and last baby. The first we got pregnant the first cycle and it happened a lot faster than we expected. For this time I’ve been tracking very closely and today I’m about 9dpo and I’m having some bleeding. AF isn’t due for a few days still and it’s definitely light compared to my usual and more pinkish brown in color. Would this be considered implantation bleeding possibly? Tests are saying negative so far, so I don’t want to get my hopes up, just curious if anyone else had this happen and get a positive after? I never had implantation bleeding with my first baby so this would be a new experience for me if so. Thanks in advance😌
