*UPDATE* AF "due" today, absolutely terrified

I miscarried Jan 20th, had a period Feb 26th, and AF is "due" today. (In quotes because periods are typically irregular.) I am terrified of getting another negative test. I've been feeling classic pregnancy symptoms, but as most of you know, they're also AF symptoms, and I can't even tell the difference anymore. My emotions have been all over the damn place lately, and I'm driving my SO insane (not that he shows it, he's a sweetheart). I wish I could know already, but I won't take a test until Saturday.

*UPDATE*

Still no AF, but still getting BFN. I'm getting really discouraged. I will wait to take another test on Sunday, but I'm losing hope. It might be all for the best. Maybe we were only meant to have one child. I hope not.
