I've been getting faint lines (squinters) on the FRER during BFN cycles for some time now. I can't think of the last time I didn't see a faint second line on one of those tests! Sorry to say, I'd take the digi result as more reliable than a faint line on a FRER. However, if you had a clear/strong line on a FRER, that would be a different story.

As mentioned above, it's the digis are supposed to be less sensitive, but I had the old style ones (without conception indicator) pick up hcg levels lower than the documented sensitivity.

I'm sorry to hear you have started bleeding. I hope it's not an ectopic as you fear.
