No sign of period (due today) but BFN, am I out?

I’m due on today and usually get horrendous cramps but haven’t had anything, my boobs have been so sore especially my nipples.

I got up with my 1 year old at 4am and completely forgot I was meant to take a test so had a wee, waited a few hours and have take a clear blue one but no 2nd line.

Am I out???!
