Um, FRERs....I know they are expensive, right? I actually had 2 leftover from last cycle, so so far I've only bought 1 two pack this cycle. I also used a handful of walmart cheapies/dollar store tests, and I did get a super squinter (but it was fat, and pink!) at 10dpo, but I didn't have one to do 11 dpo this morning.
I have tried ICs, $ store tests, Answer brand tests, digitals, and for all 3 of my pregnancies FRER has been the one to get a good positive early and not leave me scratching my head wondering (for too long anyway!).
