Before I begin, I need to point out I am a POAS addict - there is little I don't know about POAS. I'll get through hundreds 
a lot of internet cheapies per TTC cycle. I've also been pregnant six times, so I know what positives look like and where etc etc.
Okay, with that out the way! Last week I bought a twin pack of Alvita tests from a Boots outlet store as they were cheap. I'd never seen them before, but being a POAS addict, I'll wee on anything especially if I haven't done so before. Err, within reason.
I was 8dpo yesterday and thought I'd try one. I used it according to the instructions (dipped in a cup as usual) and a clear thick pink line showed up. At which point I am not sure as I was so sure it was going to be negative I wasn't looking, but it was there an hour later when I went back to look. We're talking 15% as dark as the control line, and strong enough to clearly see at arm's length. The sort a husband could spot 
I was unconvinced though, because none of my eBay cheapies showed anything. Nor did the First Response I obviously used next. It claims on the box to "test from when your period is due" which usually translates to 25miu - the cheapies are all 10miu naturally.
I tried the other one in the box a while later and got nothing within the time limit, and the next morning there looked like a really faint shadow. Nothing at all like the thick pink line on the original one.
24 hours later and still no BFPs.
I thought I would post this because I did a lot of searching on false positives for this brand and found nothing much on the brand at all as it is quite an unusual one. The tests seem to be offered by various IVF clinics which is a bit worrying. Hopefully this post will be of some use for someone.
As an aside I've had a whole bunch of pencil thin lines within a minute on ClearBlue Easys this month which is disappointing.. never had this happen before. Also had a pencil thin line on a Boots own brand blue test (said I was obsessed!). This is definitely a cycle of false positives 
and it's costing me a fortune in cross checking with FRERs. Normally I won't break them out until I see a line on a cheaper test.
I'm not out yet as am still 9dpo, but I know these are false positives because cross checking with six other brands, including FRER, and still no lines anywhere 24 hours later can't be wrong!

False Positive warning - Alvita tests

Definitely not a chemical! I had one of those last month, and that showed up on the FRERs and all my other tests. This was just the one test, out of around 30-40 tests, nearly all cheapies, that I tested with yesterday. I'm sure I'd have seen something else on something (Clearblues aside) The cheapies have never given me a false line like this in all my years of TTC.
I think I was using the Clearblue Plus. Most blue line tests are quite "famous" for their pencil thin false positives. I've had real positives super early on them before, before the internet cheapies, which is why I use them occasionally at this stage. The real positives have no pencil thin blue line, just a very, very faint wide light blue line, as you might expect!
I had similar with the Boots tests that have a blue + as the positive. I got two false positives with the two I used 
so j have never bought any more!
Oh yep, it could have been an evap.. but it was very dark for an evap and it had colour - evaps are usually grey/colourless. The evaps I've had on other tests have all been really, really faint and have no colour. I'm pretty sure it would have shown up before the time limit at that darkness and colour - in my experience any grey evaps show up well over an hour later.
Most state to ignore anything after 5 or 10 minutes, let alone 30 minutes and I agree the result is invalid. But in my experience (and we are probably talking a few thousand sticks over the years) pink thick lines that come up after 10 minutes are the beginnings of a BFP. I've never seen a coloured line come up after the time limit or within an hour that wasn't a BFP.
This is the first time I've ever seen anything like this so I thought it was worth a mention. I know people like to "trash dive" even though they shouldn't, and I'd hate for anyone to get their hopes up because usually something pink does mean a BFP, no matter how late you see it.
