I am NEVER late, it’s always earlier than expected, all my tests are coming back BFN

I have had spotting (only a tiny amount when wiping, and only really once a day) which seems to have stopped and have had no AF cramps to indicate it’s coming. Took another test today (clearblue digital early) which again was BFN

I’m not stressed or anything like that otherwise I’d put it down to that!

What’s going on 😩 I’m 14DPO anyone had anything similar?
