My FRER's came in the mail Friday, so all though I know it was way to early I decided to go ahead and use one.
The freaking thing was positive! DH was about to have a heart attack because it was 6 DPO, and he was convinced I had a litter in there. Till I explained to him that they are more sensitive than the IC's and most likely it was just the trigger. And to save freaking out till I tested again on Saturday and then if it was darker, he could start freaking.
Well Saturday both the FRER and IC were negative, checked again Sunday and it was negative. So at least we know the trigger is officially out of my system. Wednesday is my key day- if I don't get a BFP then I know that I'm pretty much out.
