How quickly did your tests get darker?

Sorry, ladies. I'm a nervous wreck. So afraid of losing another pregnancy. Anyhow, how long did it take for your tests to get darker? I took a frer yesterday at 11dpo and another today, and the lines look about the same. Is that a bad sign? Don't think I can relax until I get some darker positives and blood test results.
