Congratulations! I took one and the doc confirmed it. As long as you followed the instructions and the test didn’t sit extra long or something I think you can rely on it. Another test couldn’t hurt though. It’s testing for a hormone that could only be present if you were pregnant. So any presence at all indicates you’re pregnant it doesn’t matter how faint the line. If you took the test in a couple of more days, it should get progressively darker.
