Lyndzies, honestly I think zen is overrated . That said, wait until tomorrow morning to POS, because otherwise you'll just keep thinking - oh it wasn't first thing in the morning, maybe it was too diluted etc. Or at least that's what I would think!
See, what I'm thinking is if I get a 3-pack of FRER (SOOOO pissed that my $tree stopped selling HPTs, btw!) I can test today, 13 dpo, adn then if AF is MIA on 15dpo.
Don't you love how I'm trying to justify my obsession? Lol.
