Is this just me?? I feel like I'm the only one who just stares at my BFN hoping for that second pink line to suddenly pop up!! And I know I'm testing early but I tested early in July and got two pink lines (ended in a miscarriage).  I'm hoping that this isn't a definite sign that I'm out this month. AF is due to arrive in 4 days - I'm just nervous that I should have some time of VFL by now - but I have nothing. One lonely pink line 😔
How long did it take anyone to get their BFP, how many DPO? Did you get your BFP right away, day of missed AF, several days after missed AF?
