to have used an expired pregnancy test and now be unsure whether to trust the result?

Have been TTC our second child for just a couple of weeks, and as I had an old pregnancy test in the cupboard I thought I'd see what happened if I used it rather than just throw it away... Well, it said I'm pregnant by 1-2 weeks (it's one of those Clear Blue digital dating ones). grin

I'm really trying not to get too excited though as:

1) the test had an expiry date of August 2012;

2) I've tested too early (I'm about 5 days away from the date my period is due, and I know even the earliest tests say to use them no more than 4 days ahead); and

3) I've tested at night (aren't HCG levels supposed to be higher in the morning?).

So I know I was a bit stupid to do the test knowing that the result would be unreliable... And now I'm struggling to stop myself getting my hopes up. Especially as with DD1 it happened straight away so maybe it could be the same this time...

I know I just have to wait until next week and then do an another, in date, test. But surely an expired test would be more likely to give a false negative than a false positive...?

I would be less likely to trust a neg result.

I think you're up the duff congrats! flowers

I think false positives are incredibly rare.
You're pregnant.

FitzgeraldProtagonist Tue 24-Sep-13 22:26:59

Am sure even expired digi never lies. Congrats!

Laura0806 Tue 24-Sep-13 22:27:03

I suspect you're pregnant too! Be very strange for it to give a positive result even though it has expired

ChippingInNeedsSleepAndCoffee Tue 24-Sep-13 22:29:03

I would have thought, if anything, a false negative would happen with an out of date one...


Maryann1975 Tue 24-Sep-13 22:29:44

Get another test tomorrow and try again. Then you will know. I would think if they have an expiry date on them, it's probably because they are not as reliable after that date, so I wouldn't like to say if the result you got today would be true or not. In an in date test I didn't think you could get a false positive though? I shall keep my fingers crossed for you though.

AuntPittypat Tue 24-Sep-13 22:31:21

You lot are supposed to be helping me not get excited, not encouraging me! Thanks for the congrats though - will keep my fingers crossed that they are warranted. smile

ChippingInNeedsSleepAndCoffee Tue 24-Sep-13 22:33:07

OOopsssss - sorry!


FelixCited Tue 24-Sep-13 22:33:57

If it helps.. I got a pregnant 1-2 on a cb digi at 10dpo.
Keep us updated!!

dizzy77 Tue 24-Sep-13 22:35:05

The test I used when I was first expecting DS1 was about 6 years out of date! It had been knocking around in a drawer since a very early close call when DH and i were first going out. I did go out the following day and buy the whizz-bangiest most advanced digital sort which gave the same result smile.

Congratulations of a most tentative kind.

AuntPittypat Tue 24-Sep-13 22:41:21

Will definitely do another test tomorrow and update with the result. I'll be so disappointed now if it's negative!

EmmaLL25 Tue 24-Sep-13 22:44:01

Maybe it's twins and you've really high HcG levels!

DorothyMantooth Tue 24-Sep-13 22:47:57

I agree that it's probably right - the fact that HcG levels are more concentrated in the morning points to the fact that you have a pretty high level for it to be picked up this early on (and in the evening too!) Tentative congrats!

Crazycake Tue 24-Sep-13 22:48:20

With DD3 I tested 5 days before I was due on, I just felt different. It was positive! Good luck smile

DorothyMantooth Tue 24-Sep-13 22:49:39

Also, I got a BFP with DD at least 5 days before expected period smile

Retroformica Tue 24-Sep-13 22:56:51

Have you any symptoms? Sore boob, implantation spotting, disliking the taste of tea or coffee?

AuntPittypat Tue 24-Sep-13 22:58:14

EmmaLL25, twins?!! shock

It's really good to hear others' stories of tests working despite not being used exactly as instructions say. Thanks all.

MissDuke Tue 24-Sep-13 23:00:08

I also reckon you are preg :-) I did a similarly daft thing, I used a test that my daughter had ripped the wrapper off months before, so when it was positive I didn't believe the result anyway (It turned out to be correct).

Then with my 3rd baby, I tested first thing and it was negative, I accidently left it on the side of the bath. When I got home that night it was positive....... Again, it turned out to be correct :-)

bludgerwitch Tue 24-Sep-13 23:02:09

I tested 4 days early with evening wee and got a 1-2 weeks so there's a good chance you're upduffed! Hooray!

AuntPittypat Tue 24-Sep-13 23:04:09

Retroformica, no real symptoms, but as someone upthread said, I do feel sort of different somehow. I guess I have been more tired than usual and going to bed earlier to lie awake mumsnetting on my phone. And I went out for lunch today to my favourite place where they do delicious toasted sandwiches, but today all I wanted was a chocolate brownie ice cream sundae and chips hmm.

kali110 Tue 24-Sep-13 23:07:26

Your more likely to get a false negative than a false positive.
Do let us know!

TedMoseby Tue 24-Sep-13 23:07:51

I agree with everyone else! A positive is a positive.

LegoAcupuncture Tue 24-Sep-13 23:10:58

Tentative congratulations

Gambia Wed 25-Sep-13 07:44:34

I got a BFP on an expired clear blue digi too and it turns out it still worked... lo is now 6 months old! Think I took it when my af was due though. Then had to try about 10others all of which gave very faint lines as I didn't believe it because it had expired!
Keeping my fingers crossed for you!

DigestivesAndPhiladelphia Wed 25-Sep-13 08:14:38

I tested 6 days early with one of those tests and got 1-2 weeks... It was twins grin

When I tested a couple of days later it had changed to 3-4 weeks so I suppose that was a clue rage levels were rising quickly.

DigestivesAndPhiladelphia Wed 25-Sep-13 08:15:47

That was meant to say "a clue THAT levels were rising quickly" confused

gordyslovesheep Wed 25-Sep-13 08:19:46

Did your rage levels rise quickly though with all those hormones!

Fingers crossed op x

JessicaRRRabbit Wed 25-Sep-13 08:30:05

Morning all. Fx for you OP <hands round brew and marks place. >

DigestivesAndPhiladelphia Wed 25-Sep-13 08:43:28

Gordy, I think that was a Freudian slip grin

BlackeyedSusan Wed 25-Sep-13 10:42:26


retest please. people are wwaiting. pots are not getting washed, cleaning is not getting done...

Lweji Wed 25-Sep-13 11:04:11

Do retest.

The test is a year past his expiry date and could give false positives.

CrispyFB Wed 25-Sep-13 11:16:42

I bought a bunch of cheap expired Clearblue digitals on eBay a while ago, intending to use them to "date" any pregnancy week by week if I got my BFP.

I got my BFP at 9dpo, by the "textbooks" that would be 5 days before my period is due. The expired Clearblue came up positive that evening, just like yours. You could barely see the line on the First Response at the time! I'm now nearly 14 weeks.

From past experience expiry dates just make negatives more likely, not positives.

But.. test again to confirm of course.. but if I had to bet £100 I'd say you were pregnant! grin

CrispyFB Wed 25-Sep-13 11:17:06

Forgot to add - the tests were two years out of date!

SoupDragon Wed 25-Sep-13 11:22:11

Just a word of caution and not place marking at all I imagine the digital ones perhaps have the capacity to go wrong in the digital part of the test stick and give the wrong result in a way that the spot-the-line tests don't.

But clearly you need to POAS again regardless!

AuntPittypat Wed 25-Sep-13 18:45:38

Well.... I tested again at lunchtime today with a brand spanking new test and.... It said exactly the same! So it looks like all you wise people were right, I am officially upduffed! grin

Now begins the paranoid wait until first scan to check all is ok. And to check if it's one mini Pitty or two. This talk of twins is scaring me!

So happy! grin grin

SoupDragon Wed 25-Sep-13 18:46:49
