I totally get the worry, this is confusing! So here's the thing: a faint line on a home test is actually still considered a positive line, especially if it showed up within the testing window, because it means hCG hormone is present in your body. The tricky part is that hCG levels can be super low in very early pregnancy, so the line stays faint, and sometimes the urine and blood tests at the clinic just don't pick it up yet, timing matters a lot. Someone in my mum group went through exactly this, and her blood test came back negative the first time but positive a week later, so the pregnancy was just caught too early.
