Faint positive or possible evap lines?

[Mumofawarrior12]

Took a test yesterday Lloyds pharmacy own brand pink dye test... and got a negative but then when I checked after around 15-20 mins there was a faint line.

Today iv been to Sainsburys but only ones I could get were sainsburys blue dye ones pack of 2.
After around 8-10 mins I think there may be a faint line... but both have showed up after the recommended time scale ??

Any experience and can you see the lines? Or is it me?

When is your period due?

[Mumofawarrior12]

My app is showing I am 4 days late but my cycle lengths vary each month.
I thought if I was then the lines would be much darker. X

Done another blue dye this morning which was negative but then showed a very faint line after 20 mins... but been for a clear blue today and it's negative so I guess if I was it would have showed on that one?

I know it's easier said than done, but you need to wait a couple of days and take another test, preferably a first response early response - don't get the first response rapid results as this is much less sensitive.

[Mumofawarrior12]

I can't get hold of a rapid response one hun. Tried local supermarkets and they haven't had them xx

[HariboFrenzy]

In that case I would wait at least a couple of days before testing again with fmu on a supermarket test. I think Sainsbury's are a bit more sensitive than some of the others

Asda own brand early test is very sensetive if you can get hold of one, actually gave me a positive before a first response early test.

[Mumofawarrior12]

Is 10ul more sensitive than 25ul. How does it work?

[Mumofawarrior12]

Thanks jinglebell I have one more clear blue left dunno whether to do it tomorrow or wait a few days.. day 42 today.. last cycles have been 37 days.. don't get it xx

I didn't get anything until I was 7days late, and my period is very regular. So wait until you're a week late if you can!

[Mumofawarrior12]

Really? sizeofalentil everyone is so different. Thank you. So by your dates did you ovulate late. X

25 u is higher. a standard test will detect hCG in the urine at concentration greater than or equal to 25mlU/ml. concentration of hCG in non preg women is normally 5.0mlU/ml.
excessive fluid intake may dilute the pregnancy hormone and may make it difficult to read so first wee of the day is best b/c contains higher concentration of hCG
good luck love x
