i was just looking on the internet cause i had a bfp today at 11dpo and im so nervous that its not really a positive because its just too good to be true and i found all these pictures of evap lines on different brands of hpt's and im scared that my "second line" is an evap line...it was up with in a minute and then got a bit darker over 3 mins......how long does it take for an evap line to appear and what exactly is one?

As long as you checked your test within the time frame stated in its instructions you have a positive result. Evap lines show after the allotted time frame and often times are colorless (gray).

What's an evaporation line? Evaporation ("evap") lines result with the test's antibody strip just looks slightly different than the space around it. There is a line of antibodies (usually made from mouse cells) in the Control and Test section. The Control line binds with any liquid and turns pink (or blue, in tests using blue dye.) The Test/Result line turns pink only if pregnancy hormone is detected. If not, the moisture passes over this strip and does not turn pink. It may, however, become more visible when the light hits the moisture on the strip-- it may appear gray, colorless, like a "dent" in the test, or like a "ghost line." It may appear at any time-- as soon as the urine hits it, after a few minutes as the test absorbs the moisture, or after the 10-minute time limit. It may appear when the test is drying, or after it has dried. It may disappear as the test is drying, or after the test has dried, or not disappear at all.
The simple fact is that there is always "something there" that is slightly visible-- it's simply the antibodies on the test that would turn pink in the presence of hCG. When the test becomes wet, or as it dries, or after it dries, the antibody strip may become more visible. Therefore, all tests may have them. It is not a defect; it's just how tests are made.
A real positive is identified by its color (pink or blue, whatever the color of the test's dye is) and its appearance within 10 minutes of urinating on the stick. A line that appears after 10 minutes, regardless of color, must be considered an evap line and is caused by the test's chemicals changing. HPT's are rapid assay diagnostics, which means any results appearing after the "rapid" time limit of 10 minutes are invalid.

I would say it probably is a positive. All the evap lines I have had have been grey (not the usual blue or pink that it should be) and have been slightly thinner than a positive line. Also, as it appeared within a minute this would also suggest a positive as this is when the result should appear. Evaps usually take longer to appear as they generally appear when the test is drying out.
Take another test just to be sure but I would say you are pregnant! Congrats!

Evap lines show after the result time window is up (usually most tests say do not read results after 10 minutes) a positive result can be light at first and darken over several minutes as more HCG is absorbed into the test.
I suggest you retest just to be sure, but given the fact you had a line at one minute even a faint line I would suspect you are infact pregnant!
Congrats!

Since each brand is different read the box for details. The usual rule is-. Even a faint line is a positive. Congratulations. Next thing to do is schedule a appt with your clinic for a blood test to confirm your pregnancy. They can usually get you in within a day or two since you wont have to see the Dr yet.

because of the fact the 'line' regarded interior 10 minutes and is the ultimate coloration, i don't think of that is an evaporation line-- that is probable a faint helpful. whether, on account which you had to take the attempt aside (?) to work out it, i does not have confidence it yet. attempt back in an afternoon or 2 or 3. (despite the container recommends) solid luck! wish you're pregnant!

The best thing to do for now is take another hpt, then call the dr
