Hi all, I got the faintest of all squinters on an FRER this morning (15dpo). DH can't see anything and thinks I'm deluded, but I know I can see something and I know I'm pregnant.
Unfortunately, exactly the same thing happened over Christmas: I had a real squinter at 16dpo, then a BFP on a digital and a Superdrug test at 19dpo. I tested again at five weeks with another Superdrug test and the line hadn't got any darker; I miscarried at six weeks.
I suppose I'm looking either for reassurance from people who've had late BFPs which turned into viable pregnancies, or stories from people who've been in the same boat!
