I am 17 DPO and still no AF... I haven't seen a BFP yet and I used a FRER right when I rolled out of bed this morning. I thought that they were supposed to be 99% accurate from the first day of your missed period, but I have yet to get even a faint line so I was assuming I am not pregnant. I figured I must have misread my cycle or something. My friend told me her sister didn't get a BFP on a HPT for over a week after her missed period though. I looked it up on Consumer Reports and it said the same thing: that even FRER(and all others) was not always correct in saying that it was 99% at finding hCg and it took a number of women longer to get a BFP. I guess I am posting this b/c not knowing is making me antsy. I almost wish I had AF show up instead of getting my hopes up if I am not pregnant.
