1st Trimester

Faint Positive Wondfo/Negative FRER

13 DPO
I had a very faint (but definitely there) line on the Wondfo test. 30 minutes later I picked up an FRER from Meijer and did the test and it was clearly negative.

I know there are evap lines with Wondfos, but I checked the strip within the 5 minute mark.  Does anyone know about the sensitivity of Wondfos vs FRERs?  I don't know if I should have peed on a second test that quickly and in the afternoon also.

I am assuming I've got a negative, but man... I've never had a line on a pee stick before.  Any ideas?

Re: Faint Positive Wondfo/Negative FRER

  • I did a wondfo 6 days before my period and it was positive! Then a clear blue digital and it said pregnant 1-2 weeks! Good luck :)
  • Did you do your Clear Blue immediately after the Wondfo?

    Best wishes!

  • No I waited over 3 hours to help my hcg get higher again. The longer you wait the better result I think.
  • Check again first thing tomorrow.  Good luck!

  • Okay, thanks for the advice! I've been doing some researching and it seems that some people with negative FRERs end up pregnant and some don't.  I'm going to assume it's negative... or at least tell myself that I am.
  • I agree to take another FR with FMU... It's the most concentrated and it will give you the best result. Good luck!

  • When I got my BFP I used both tests at the same time. The Wonfo was faint and the FRER was a dark positive right away.

  • There have been some bad batches of Wondfos lately, including some that would give false positives.

  • I would wait to take them with FMU. The FRER are def my favorite.
  • I used FMU on the Wonderfo at DPO 14 the line was so faint I thought I was imagining it.  I decided to also test with a Clear Blue digital, not even a minute later it said pregnant. Both the same urine I always pee in a cup.
