I'm 16dpo, tested negative at 13 and 14dpo (stark white) but AF still hasn't shown up. I haven't had any signs that she's on her way, apart from my cervix being low and hard - although I've heard that's an unreliable way to tell.
I had sore nipples from about 6-12dpo, which is unusual for me, but nothing since then. I had some very weird cramps in the evening of 14dpo (a painful, almost a fizzing sensation), which made me think AF might be arriving, but she didn't.
Has anyone had similar and gone on to get a late BFP, or should I just assume AF is playing tricks and will show up when she chooses?
