FRERs giving dark evaps and possibly false pos (XP)

As seen in my post below, I got a visible line at 10DPO that looked pinkish, and was read within the 10 min time limit.

Yesterday when I retested and got a ghostly gray line, I did some googling.

There have been lots of reports of dark gray and even pinkish evaps on the new "6 days sooner" FRERs. Some women say they see a light gray line even before they pee on the stick! I am not sure if this applies to the "5 days sooner" tests, if those are still even around.

So, the typical wisdom of "If you see a line on a FRER you're pregnant, because FRERs don't give evaps" isn't true anymore. Just wanted to save someone the confusion (and disappointment) I had.

How disappointing! I was convinced that was a true positive! I am so sorry.

I tested with an FRER the day AF was due and it was a negative. I went out and drank later that night (It was my birthday, and DH and I were on vacation alone!) 4 days later, on a Walmart cheepie, I got a very clear BFP. So yeah, I am not a fan of FRERs either!

I got an evap on a FRER about 4 months ago too. I took it apart because I was so annoyed and it looked like there's an indent on the back of the tests where the dye would catch that leaves the evap. Sad

Sorry it didn't work out this month!

I'll let you know about my experience....I had a very light FRER at 12 DPO that was very accurate. Accurate enough to detect 7.1 HCG. And everyone on DYSAL agreed that it was positive. I tested every day for a few days after that and it was still visible, but getting lighter. The last day I tested, I had a very very very light line that looked a bit grey. That was the day my HCG came back as negative. Since I have to be monitored early on, I have the benefit of having HCG tests to compare it to.

I saw the test you posted and there was definitely a line. I would be inclined to say you may have had a chemical pregnancy.

There is such a huge rate of chemical pregnancies that people would never know about if not for these early tests that detect such low levels.

I wish you better luck this month, at any rate!
