Oh Honey, that ain't no residual Pregnyl line there Girl, that's a bloody "No Doubt About It Up The Duff" BFFP line!!!!
Congratulations, you're Preggo!!!!
I know you're holding off formally letting loose and celebrating until you get formal confirmation from your Beta's Luv, but I'm happy to go out early on this!!!
