A faint positive line on a home pregnancy test can often indicate a positive result, especially if the test is within its reading time. This usually means there's some level of the pregnancy hormone hCG detected. However, to be more certain, retesting in a couple of days can help, as hCG levels typically double every 48-72 hours. Factors like diluted urine or testing too early can cause faint lines. False positives are rare but can occur due to factors like recent pregnancy loss or certain medications. If you're still unsure, consulting with a healthcare provider for a blood test might be a good next step. Have you considered checking the instructions on the test for more details on reading faint lines?
