They do fade, but not until a few weeks later. Ones i have from just a few weeks ago are discolored and faded.

But I have ones from years ago that are intact. I think they are made differently today.

Don't read a negative test after 10 minutes means if it's negative at 10 mins, it's negative and don't keep checking it to see if it's turning positive.


+1. I still have the positive tests from my pregnancy. I don't think they fade, but it could be that it was too early to test, depending on how sensitive your test is.

yes it could fade. Just test again in the morning first urine.

The box said it didn't matter, although the am urine was strongest. I just re-read directions though, and it said not to read a negative test after ten minutes. What does that mean? That it could fade?!

Hugs to you, OP. I'm not sure, but don't they recommend testing in the AM? (Specifically, the first time you urinate?)

OP here. Well I broke down and tested. No second line . I'm 8dp5dt so I assume it would show up if positive. My only hope is that I waited over 30 minutes to look at the stick (because I'm a mega wimp), and maybe the line had faded?!? But I'm not optimistic. This is my first bfn and I'm crushed.

Those tests are extremely accurate and also very sensitive. lord know why they are so vilified by REs.

I found that doing testing myself (negative and positive results) were much less stressful if I knew the results beforehand. Waiting for that call is torture! The only tough spot is when you get a BFP, but it turns out to be a chemical. But I test at the same time every day to watch the line get darker (it's an addiction)! I've always gotten positives by 6dp5dt or 11 dpo.

OP here- thanks everyone! I guess I'm trying to hold off on testing because when I did IVF I didn't test and got a bfp, so I'm being superstitious about it. Silly, I know. I shouldn't have bought the test because now it's just sitting on my dresser staring at me...

HPTs were always reliable for me - both negatively and positively. You do need to wait long enough post transfer for a pregnancy to be detectible of course, but if you are 9 days post transfer (or so) then you should get an accurate result.

I was always glad I tested first - especially when it was negative - as it allowed me to better manage the news from the doctor's office when they called me at work.

Good luck!

There is no such thing as a false positive unless its the trigger.
I got a positive at 9dpo. My beta the next day was 220, I think. So,in theory, a HPT should've shown positive at 8dpo or even 7dpo.

I took a HPT 9 days after my day 5 transfer and it was positive (and correct). Depending on where you are in your cycle - I would go ahead and test!

Progesterone injections cannot give you a false positive. The only thing that will give you a false positive is if you had an HCG trigger shot and that is still in your system.

I am in the eternal 2ww and bought a HPT yesterday. I'm trying not to take it and wait until my beta on Tuesday but I don't know if I'll make it. So my question is, for those who took a HPT- was the result the same as your beta test? I'm on progesterone injections, which I know can give false positives (so I've heard). I did a FET fwiw.
Thanks!
