I do. I feel like a loon. Today is 14 dpo for me. AF was due today. Instead I have had the most annoying back ache, legs ache, no energy, mild cramps and creamy cm. I'm annoyed. I tested with FMU with a FRER and get a blazing white BFN. I know I'm out, but now I'm just ready for AF to show up so I can start a new month.
