Help me need advice!!!

hi ladies need some help please

was due my period last Sunday and I started spottin on Wednesday light pink brownish only when I wiped goin toilet it was on and off until Friday morning when it completely stopped I was wondering if that was maybe implantation bkeeding as it’s unusal for me to bleed like that, and the week before I was due my period I also had a shooting pains one night All night in bed that came and went was fine next morning...

took a test but it was negative, if I was would I still be too early to test
