Persephone-how long is your luteal phase normally?
Perse-im sure you are well aware (you seem like you inform yourself of things) that you lp usually stays consistent so dont be checking out of this tww yet. If you were feeling implantation symptoms only a couple of days ago a pos hpt wouldn't happen for at least a day or more. They say roughly 6 days from implantation for a pos hpt.
