I was just wondering...

Brianna • Mommy to daughter Kinsley (almost 4). I have alopecia areata. 23. Student. Elementary teacher to be!

has anyone gotten like a obvious BFN and then the next day like a clear as day positive, not a faint line but like wam bam line in your face? Af is due on Friday and I tested today and there was no doubt about it negative no faint line anything so would it be pointless to test tomorrow?
