I got AF 4 days late ( I believe that was stress induced) it lasted only 4 days and was kinda fainter that usual (I usually go
for 5-7 days
heavy first two then taper off the rest) but I did cramp more that usual as well.
So sorry to hear about the bfn, I know how it feels I was so hopeful it would work the first time for me too, but think I psyched myself up too much and was telling everyone. This time I'm going to keep it between me, dh, and dr. Less stress that way I feel.
