False positive CB Digi opk

Saturday, June 16, 2012

I never thought this could happen, but it happened to me this morning.  I am a big fan of the Clearblue Digital Ovulation Tests (aka 'smiley face' opk).  I have had very good luck with them so far.  This morning I started my usual testing a few days before my CM is even fertile.  I peed in the cup, stuck in the stick for 15 what I thought was 15 seconds (by counting one one thousand, two one thousand, etc.), set it on the counter, and then walked away to my computer.  I started peeing in cups instead of right on the stick because, since I use FMU, I find myself way too uncoordinated when I first wake up to be able to aim at the stick.

Fully expecting a big O, I returned to the bathroom to check and lo and behold there was a smiley.  WTF?!  It is only cd 11.  I immediately ejected the stick and saw a tremendous dye run.  I got out a Wondfo opk, dipped that for 3 seconds, and then watched it like a hawk.  A very light test line...definitely not my usual positive.  Luckily I hadn't thrown out the urine yet so I waited for the CB Digi to get back to a blank screen and then I got out another stick (I cringe thinking about the cost of this).  This time I got my cell phone stopwatch and used it.  15 seconds later I laid the stick down on the sink and walked away.  A few minutes later I came back and it was indeed a big O.  I ejected the test and saw that there was very faint test line.

A few things...

1.  I have heard that CB Digis NEVER have false positives.  I did a little Internet research and I have found some similar stories (and pictures) of girls that have had false positives due to dye runs.  Many suggest calling the company to confirm.  I wonder if they would send me a free test kit due to this waste of an extra stick.

2.  I have had similar dye runs cause actual errors on the test.  I feel like this one should have caused an error so now I am wondering if this electronic test stick is screwed up.

3.  Last month when I got a smiley, I also had a strongly positive Wondfo opk.  This was not the case this time.

4.  Last month I ovulated on day 17.  I am feeling like it might be a little earlier this month, but not day 11 or 12!  I don't even have any fertile CM yet.

Here is the pic...what do you all think?  Totally a false positive right?  Have you ever had a false positive due to a dye run?

  1. I've gotten a false positive before with the electronic tests and it was because of a dye run. It looks like that may be what happened here.

    But I would DTD just to be sure! It can't hurt to have a little fun! Put that new waxing to good use! :)

  2. If you do think it was a CB problem, then it's a good idea to call them. I called CB about an issue with the fertility monitor sticks, and they offered to send me a replacement box right away.

  3. I would call them...and if they send you free tests, than its a bonus! I would say its a dye run, especially if you had two negatives with the same urine.

  4. you cannot have a false positive with CB digital because it compares the readings from what it had before. and you are Not supposed to look at the stick to make your decisions, doesn't matter even if its "smeared", until you know you handled it properly and did not shake it while it was "calculating" then the result is accurate. Since CB digital compares results from before, if you already got a smiley and use the same urine to test again, you will get a big fat O and not a smiley because obviously in the same urine your LH levels have not increased. It is possible to get surge in LH before you get your CM because it can take up to 24-48 maybe even sometimes 72 hours for one to ovulate AFTER the PEAK of the LH surge. you might have just caught the beginning of LH surge, so its possible that it would have peaked on CD 12, and so 48 hours later like CD 14 you might ovulate. hope this makes sense
