The line appeared after the 10-minute time limit. Is it still positive?
[/i]No. You can’t rely on any test results that appear after the time limit. There is a reason the tests have a time limit– and torturing us is not usually that reason If a line appears in the “results” window after the time specified in the directions, wait a couple days and test again. HPT’s are rapid assay diagnostics, which means any results appearing after the “rapid” time limit of 10 minutes are invalid– after this time, natural changes in the chemicals may cause lines to appear. (Please don’t e-mail me to say this happened to you and you really were pregnant. The odds of having this occur and still end up pregnant are the same as the odds of having any false negative and later detecting pregnancy. In other words, the test is still considered negative; some women testing too early get false negatives.

See A Cautionary Tale and The Tests for examples of “positives” appearing after the 10-minute mark when the tester (me!) was not pregnant. See FAQ 7 for more info on evaporation l
