Faint bfp for 4 days?

On a whim I took a target brand test around 7dpo and it came up faint positive, then I read how horrible those tests are so I got a frer and also got a faint positive...then I read how horrible those tests are....I got some assured brand dollar store tests that the line was so faint on it I could barely (and I mean like almost didn't exist-and maybe it didn't?) that I took the next day. I'm now about 10/11dpo and took walgreens brand and got super faint positives (blue dye and of course everyone hates those too) and another frer that looks the same as it did 4 days ago....(face palm)

i know 7dpo is super early to test and I didn't expect to see anything at all, I was just having cramping and pinching going on so I figured why not....but I've read so many things about getting false positives on just about every brand now I'm not sure what to trust.

Anyone else get faint but visible frer tests that went on to healthy pregnancy? (Between 7-12dpo) Even when other tests are showing neg or super faint? All lines appeared in the 3-5 min window of time and look exactly the same on frer (4 in total).
