The tests are MOST ACCURATE when used in the morning. Why? Because your urine is more concentrated - you don't drink fluids at night. For a given sample size the hormone hCG, which the test looks for, would be higher.
Cheap tests are also unreliable.
You are VERY likely pregnant. False positives are VERY rare. False negatives are VERY common. Note: the test "defaults" to negative.
