Confused

Idk what’s going on with my body y’all. I guess I’m just testing too early right now. I’m 4 days away from period. That would be I think 10-11 dpo according my period tracker. But I can only get positives on one brand but others I can’t see anything. I’m not sure if it’s my hcg maybe or if it’s the test but it’s obvious that it’s a faint positive on that one brand. I’ve had 6 of those show up as really faint.
