Test looks positive but I have been spotting heavily since 8 dpo

So I just started intentionally TTC this month (before we were just not preventing) and at 8dpo I got a super super faint line on a Walmart cheapie, but it didn’t appear until way after the time. I also started spotting that day and the spotting continued so I assumed I was out. It got heavier on 9dpo, with literal droplets in the toilet (sorry TMI) and continued through 10 dpo. Today I am 11 dpo and the spotting is still there but lighter. So I took a clearblue just to solidify in my mind that my period was coming. But it came up a faint positive. Now I’m worried that I may be early miscarrying. Has anyone had several days of spotting and it was just implantation bleeding? The blood I saw was definitely mixes of red and pink so I assumed I was out. Just very confused by this test!
