No BFP until AF??

Aubrey
The waiting... UGGGH!! AF due on Dec 2. I had a +LH surge on Nov 16. Taken HPT twice, on 11/26 & 11/28 - all negative. Feeling tired and rundown, a little nauseated yesterday, but no sore boobs or anything else.
Has anyone else had a similar experience who didn't feel any significant symptoms and only tested positive after a missed AF?
