What do you guys think?

Hey guys! I need some thoughts on this. So on August 28th I had a light period and then it ended on like the 31st-1st. Then on September 8th I started spotting this weird brownish stuff and it wasn’t a lot. It lasted for about 2-3 days. Thought of the possibility of implantation bleeding but I had just had a period? So I took a test this morning and it looked like this but then a couple hours later I took two more and they were negative? This was all today. Could it be a false positive? Should I even take one in the morning or just consider it negative?
