I'm just a little concerned that FRER isn't picking anything up.
But the more I think about it, the more I remember that in ALL of my previous pregnancies, the blue dye tests were ALWAYS the first to look positive....I never got a +FRER until 14dpo with any of them.
Hopefully this is it!
I've been crampy, metallic taste in my mouth, congested, stuffy/runny nose, tingly nipples and gassier than usual. Hopefully those are good, non AF symptoms.
