Af due today, 10 dpo bfn

TTC #2 due 3/29
Going crazy, short luteal phase so af is suppose to be today, normally I spot one day before but haven't seen anything yet. Cramping like crazy, feels like af is on her way, but it's felt like that the last 4 days. 10 dpo can really be too early so I am hoping it's a false negative. Anyone else 10 dpo???
