GOOD LUCK 2 uuu! But if it 's coloured – then HCG is present – in whatever concentration – because only HCG can bring about the colouration of pink/blue, depending on the test you are using. So then, back to home pregnancy tests ….. And now for the famous 'evaporation lines' that so many people – and 'experts' talk about. I've been having lower cramping, tender breasts, peeing all the time and my emotions are all over the place. An evap line (evaporation line) is a faint line that appears after a negative test has dried. And now for the famous 'evaporation lines' that so many people – and 'experts' talk about.

So if you go back to the stick an hour, or two, or three or four hours etc after the test; and the 'pregnancy' strip has changed colour (pink or blue depending on the test etc), then, whilst the urine has spent several hours travelling up the stick from one end to it's other – and 'dripping out at the other end – the urine has been passing over the 'pregnancy' area all the while. And liquids like to move from an area of their high concentration – to an area of their low concentration, so, because the test-stick is sealed and dry, the urine will travel along it – to it's other end – and may 'drip-out' inside the sealed area of the stick (the bit after the test and control areas that you cannot see). Brilliant post isn't it - so what do you make of this? So, either you are not pregnant, or, if your period has stopped, then you may still be pregnant but your HCG is so low that it cannot yet be detected by the test. Basically I ended up doing 3 pg tests this morning, the first one had a really faint so I did another, that was the same but then 3rd one is barely visible..I'm so confused, going to retest on monday because if I am I've been told I need emergency appointment at st marys for bloods etc sorry for the ramble! Going back to the test-strip; the 'pregnancy' line contains different molecules to the molecules of the 'control' lines; and the molecules in the pregnancy line/strip (the pregnancy test-assay) will only react – and change colour – in the presence of one other molecule; and that is the HCG hormone. ? If you're trying to get pregnant, get support from others doing the same here. This is page 1 of 5 (This thread has 121 messages.). This happened perhaps 10 seperate times (different months) and I was never pregnant at any point in those cycles.3 DC down the line I know now to avoid blue dye tests when initially testing for a pregnancy. I have already said that the control lines react to molecules found within normal urine, and, when those molecules pass over those control-line areas (control 'assay' areas) then the molecules come into contact with other molecules within the control assay and they bind together. I have had 5 IC's with faint lines and 2 superdrug tests with faint lines. If you are seeing "faint" pink or blue then its probably a positive. Think it was 11/12dpo! My evaps always stayed. And indeed, the next tests proved that she was. But it wont turn pink or blue. 2 answer your question no they don't go away as far as I know. If it's faint, then HCG is present in very low concentration, and if it is a dark coloured line, then the concentration of HCG is higher. Do Evap lines disappear? I've also had chemical pregnancies. It's so hard to know! An evap line on a pregnancy test means nothing, so it has to be discarded. Moving on... sometimes fertilisation occurs and HCG is produced for a while, but for some reason, the body detects that the pregnancy will not be successful (not 'viable') and the fertilised egg ceases to continue to divide and develop.

If you read your test after the 10 mins then the test is inaccurate. This is the superdrug one out of the case! It's so hard to know! This process of fertilisation, followed by a very early termination is known as a 'chemical pregnancy', and many women can have these, whereby the woman is sure she is pregnant, but then she later has a period – even though a home pregnancy test might have shown a faint or clear line in the first couple weeks or so – and hence is why some women are left wondering why their period returned. Also, it may still take a couple weeks or so for the 'symptoms of pregnancy' to stop altogether. Still have questions? And on contact, two different molecules form a 'complex' which changes both it's shape and it's colour – hence the coloured control lines you see in the test areas. So the urine will keep moving until the end that you 'wee'd' on has no more urine to offer! Only the HCG can combine with the pregnancy-assay molecules and bring about a colour-change. Get answers by asking now. My evaporation line had blue in it from the blue dye and I got all excited but it was nothing see as AF arrived yesterday! Is anyone sick of trying to find a partner? Gender neutral toilet in Starbucks, and I’m livid, How do you relax when you have 10 minutes to spare? (some tests are more sensitive) If not, use the same brand you got a faint positive with and test again in a day or two, if it was indeed a positive, the line should get darker as the hcg levels get higher... Best of luck! After this time frame passes, the urine in the test dries. However, remember that the area of the test-stick that you 'wee' on is made of a very dense material, and urine will be absorbed by this dense material and will travel along the test-stick by 'passive-diffusion'. I can defiantly see a line, I was so worried when I got my BFP with dd because the line was so faint. Therefore, even if the HCG levels are virtually undetectable (but present in minute quantities), as the urine travels over the pregnancy-assay, the HCG will still be attracted-to (remember the 'chemotaxis' we talked about earlier) and will bind with the molecules in the pregnancy-assay – hence a positive coloured line showing up to several hours after the test was done.
