No. That's positive: Any pickup in the positive area is positive. That said, you should have read it as directed. If the test was dried out and you left it there for some time before reading it, then that's not a valid test. I suggest you repeat it. ...Read more

Is a evap line on a blue dye pregnancy test thick or thin?

Is a evap line on a blue dye pregnancy test thick or thin?

Thinner: An evaporation line is a line caused by the evaporation of your urine. It can show up sooner that the test time limit. If a line shows up after the test time limit has passed, it probably isn't an evaporation line--it is probably a true positive result. Evap lines can appear to be thinner than a true positive result would be. There is a LOT of information on this topic at peeonastickfreak. Com ...Read more

Took a blue dye pregnancy test and got a faint positive. Took a pink dye test few mins later and was negative. Am I pregnant? It's only been 8dpo

Too soon to test: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD.

What is the difference between a evaporation line and a faint line on a pregnancy test?

What is the difference between a evaporation line and a faint line on a pregnancy test?

Pregnancy test: If you wait too long, perhaps over 10 minutes, to read your HPT, the urine dries and can leave a faint grey line. A faint line seen at the recommended time for the test indicates the presence of betaHCG in the urine and possible pregnancy. If you had a faint positive result, wait a couple of days and repeat the test. If still only slight positive, see your doctor for a blood test. ...Read more

You tell us: Only you know which brand of test you have and what the specific instructions say about the timing of reading the results. It sounds like when you were following the instructions you were not pregnant and the test was a valid one. After the test time frame is accomplished you throw it away. You don't keep it and keep reading it as if a different result will appear. ...Read more
