To ask people who are sane if there is a line…

[ConfusedConnie9]

I am due AF a Friday and these have all been very very clearly BFN up to this last one and now I’m not sure if my eyes have lost their minds!!
i have had excruciating breast pain all weekend which I never have as well as some cramps so took a few clearblue early tests over the weekend but also BFN

Very confused

I always found those cheap tests pretty accurate. If you’ve done a few and when dried there’s a clear line there id say you have every reason to be hopeful.

Sadly this morning the exact same test couldn’t look more negative
So confusing

Not necessarily. Try another cheapie but dip for less time. You only need enough to soak up past the line.

Hang in there, I know it's hard going ❤️

The faintest line ever on the next cheapie

Not even enough to be seen in a picture although I’ll attach it anyway - hard to know if that’s an evap line as so faint although haven’t had any evap lines on these cheap tests before

Probably invisible as only visible to me in certain lighting!

I make these types of tests. Stick with the red ones, cheap is perfectly good. Digital ones are less sensitive. But you are testing very early when hCG levels will be low and will fluctuate depending on how concentrated your urine is. So just wait a few days, be patient and test ideally with first morning urine, but be prepared that it may have been a chemical pregnancy. Good luck!

Just out of interest, please could you explain why flooding the test leaves a line? ☺️

these tests use gold particles coated with antibodies, which can aggregate if the pH changes too much, such as if you have too much urine on the strip or dip too deep so that the urine itself touches the membrane rather than the sample pad. That aggregation makes the gold particles clump together so they don’t move up the membrane as well, and can get caught by the molecules on the test line even if there’s no hCG present- that’s called nonspecific binding. It’s not very common though as these tests are developed to try and prevent that happening, so false positives with red tests are more likely to be a chemical pregnancy I.e. where the egg is fertilised but then doesn’t implant properly. The blue tests use nitrile rather than gold particles- nonspecific binding is much more of a problem with those so false positives are more likely

You're still very early to test. I went through this torture, it's not worth it. Test next Monday if your period hasn't arrived.

Sorry OP I don't see anything on these tests but it's still early! Test over the weekend if AF doesn't arrive on Friday x

That's so interesting, thank you for such an amazing explanation ☺️
