Spotting at 15dpo with a very positive test?

Has anyone experienced this and it work out? I have had recurrent loss, but with he chemicals my test never got or stayed dark. It was always faint positives followed by negatives and bleeding. I had an HCG draw at 13dpo and it was 137. I’m 15dpo today and a few hours after putting in my progesterone suppository last night, I went to the restroom and when I wiped I noticed pink/red and then brown discharge when I wiped and a small amount of brown on my liner. It was mostly resolved by this morning. Now when I wipe there is nothing. I would think it’s not implantation since I’ve been getting positives since 10dpo (5 days ago)? The bottom easy@home test was a few minutes ago. The bottom one was taken this morning several hours after the bleeding. I have another beta tomorrow but I’m just a ball of nerves.
