I just brought a CB ready for wed aswell omg I thought htey was the better ones, seems even they can get it wrong.

Hayley hun are you 100% sure they were false esspecially with your sypmtoms - I hate to say that but ....

Any test can go wrong if looked at after the 10 minutes maximum.

Says: So, none of the tests gave me a false positive. However, I am very unimpressed with the quality of the tests themselves. The - line on some tests (notably Clearblue and e.p.t.) is so light it's difficult to see, even in person under a bright light.

AND

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.

Did you buy them all the same day/week? Maybe they were a bad batch

I can not see how 4 tests are wrong or how 4 tests will show positive if theres no hCG present esspecially in the 10 minutes unless they are dull & have no colour

CAT I have used loads of CB and not one has given me a wrong reading (I may have tested to early, but if PG it showed a couple of days later)........I SWEAR by them as I know a good majority of women also do! The test will be just fine babe, don't worry about it.....they are not the leading brand for nothing you know :wink:

My Doctor said that it is almost impossible to get a false positive. Because for your hcg levels to go up that much you have to be pregnant. She said that a chemical pregnancy is very common. 1 in 6 pregnancies are lost right after fertilization she said you wouldn't even know it because it just dissolves.

Too common it proved we had recurrent chemicals Was a longggg journey
