number of weeks wrong on clear blue digital?

So iv taken 2 different types of tests and have had 2 bfp! I'm over the moon.

But the second test I took was the clear blue with conception indicator. I should only be about 2 weeks since conception and its saying 3+ making me over 5 weeks pregnant...

Has anyone had one of these be wrong?

I know the work by measuring the level of hormone in your urine. Could I just have a high level and therefore its wrong? I had a really high level of hormone with DD X

Ok I don't know how those tests work but is the 'weeks pregnant' estimate definitely supposed to be weeks since conception? I know that the weeks are normally counted from the 1st day if your last period by health professionals, so weeks one and two are actually before you conceive if that makes sense.

Could that explain it?

Oh and congratulations of course! smile

Thank you prima, and no it Sats on the test that whatever result you get is based on conception results and that you should add 2 weeks for the results from your last period.

Oh yes I see, I've just read your OP again. It's early, sorry.

At both of my 12 week scans I've had my due date moved, this time they brought it forward a whole week and suddenly I was 13.5 weeks. It doesn't make sense to me as I KNOW when my period was.

Ask your GP or midwife when you go to book in and let us know. I'm not due to see my MW again for a month.

Yeah, maybe I emulated earlier than I thought. Fingers crossed it just means I have less time to wait lol. Just doesn't make much sense to my dates x

Ovulated* stupid phone

Perhaps it's twins?! You'd have higher HCH in that case!

In all seriousness, it's a rough tool. You'll get an accurate date when you have your dating scan. The important thing is its positive! Congrats.

Haha I had thought twins.. we do have twins in our family. That would be new Haha.. yeah I thought as much. Just had a look at the leaflet and that part of the test is only 92% accurate so could well be wrong.

I had a 3+ which really surprised me as like you I thought it should be just about 2. However, both scan at 8 weeks and 12 weeks confirmed that I was 5 days further along than I thought -I just ovulated earlier than I had believed.

Congratulations, and don't worry too much about dates at this stage -the midwife will go by the scan date anyway, and whichever due date you calculate for yourself now is likely to change...

I had the same thing. I knew it was under 2 weeks since conception, I was charting my temp so knew the day I had OVed, and it said 2-3 and then when I took another a week later it said 3+. I took this as reassuring that there was plenty of hCG around and it was a good strong PG.

I guess the amount of hormone measured by the test and is based on averages. You and I ditsy are above average of course smile

Congratulations by the way!
