Hi Hon

If you got 'Pregnant' on the digital screen then that is a definite! There is no point checking the lines or the strength of the lines in the digital tests as they actually test a few other things so the two lines and strength of them are irrelevant with digital tests. Here is the info from the 'pee on a stick' website:

There are two types of midstream tests nowadays. The "old-fashioned" kind displays the dye in the results window for your interpretation, and the newfangled digital test reads the stick for you and displays the words "pregnant" or "not pregnant." Important: the lines on the digital stick cannot be read the same way as other tests. Two lines DO NOT equal pregnant. Both preggos and non-preggos have seen two lines. Let the words do their job and ignore the lines!
And a bit more info:

In simple terms, the digital test stick sucks up urine like a "regular" HPT. The test has a control line like every other HPT, to indicate the test worked properly. Then there is a "results zone" where a second line may or may not appear. Here's the difference: the second line may appear even if you are not pregnant, because the antibodies in the "results zone" are NOT testing ONLY for pregnancy hormone. Drumroll please. The "results zone" detects not only hCG (pregnancy hormone) . . . but also LH (luteinizing hormone.) LH is found in women's bodies almost all the time in some quantitity. (See the Fertility Info section for the nitty-gritty.) So, depending upon where you are in your cycle, how much LH your body produces normally (which can be thrown off by conditions like PCOS), you may see a second line even when there is no hCG ("Not Pregnant.")
