I used clear blue easy digital 11 DPO and it said positive, I don't know much about the lines but Here is what I found,
What do the lines on a Clearblue Digital HPT mean? Can a non-preggo get 2 lines? What does the test measure?

After much speculation about this topic, my curiosity got the better of me. After the baby went down for the night, I got busy digging into the FDA and U.S. Patent records.

Ladies, my public service research for your enjoyment:



Most HPT's are pretty straightforward. They detect hCG (human chorionic gonadotropin, the "pregnancy hormone") in urine. If hCG is present, 2 pink lines (or a blue + sign) appear in the results window. If hCG is not present (or present in such a teeeeeeeeny tiny amount that it's not yet detectable), only 1 pink line (or a blue - sign) appear in the results window. The problem with this is, of course, that a hormone-crazed woman must read the results accurately. And for some of us, reading the results accurately means refraining from photographing in high resolution and adjusting color contrast, balance, solarizing . . . disassembling tests and holding them up to windows and/or halogen light bulbs . . . begging the test to cooperate and produce a second pink line . . . I digress. The point is, the tests results require interpretation and face it, there is some ambiguity in faint lines, time limits, evap lines, etc.

So the Clearblue Easy Digital (and e.p.t. Certainty) take away the need for interpretation with a digital display that says either "Pregnant" or "Not Pregnant." No lines to analyze. No color adjusting. No halogen bulbs. NO FUN!

When the test strip is ejected from the digital reader, however, there are lines on it. And, because it's in our nature, we peestickaholics ("Hi Meg!") want to analyze those lines. The test instruction booklet says the lines "must" be disregarded. But . . . why? Doesn't the test work the same way as every other HPT? Don't 2 lines = pregnant???

So, after the baby went down, I pulled up the FDA website and U.S. Patent and Trademark Office site and waded through FDA applications and patent documents. I was a woman with an obsession. Er, mission. And now I will share the Secret of the Digital with you.
To recap: most women will normally see 2 lines on the Clearblue Digital test, pregnant or not, simply because of the normal, average, boring presence of LH. Our naked eyes cannot determine the "shade" or "intensity" of the second line, meaning our naked eyes can't make heads or tails out of the result. When the display says "Not Pregnant," believe it, until proven otherwise. (Note: Clearblue publishes the sensitivity of the digital test at 50 mIU/mL, but when questioned on their 800 line, they say 25. e.p.t. Certainty publishes their sensitivity as 50 mIU/mL as well. See the HPT FAQ for more info on why different tests work at different times-- and also why it is possible to receive a negative result and still be pregnant.)

Good Luck

Hmmm.... I think that's the problem with digital, there's no way to pick up a faint positive. If I were you I would go out and buy a regular preggo test (regular clearblue easy is great) and that way you can compare the actual lines. Since you took the test a little early (you need to wait until you miss your period) I would take the next test in a couple days. Or you can go have a blood test done (some clinics do them for free), that would tell you with perfect accuracy. Good luck!

If you read the directions it will or should say that you are not supposed to read the test after 10 mins..I would say that these are called evaporation lines...

Look at this site..
If you dont get your period then wait a week or even two,this way you will get a way more accurate reading..
Throw the tests away ok..
Good Luck!
