15dpo - one day late

Liz

So yesterday at 14dpo I tested with clearblue bfn. Today I feel like crap! I have a stuffy nose, nauseous(not too bad) and on top of that I've been dry as a desert (no cm). I've never been dry like this in my 2ww. Has anyone had a bfn then bfp at 15, 16 dpo and so on? I think I will wait until tomorrow to retest.
