Can somebody help?

An
Can anyone explain what my chart looks like?? i ovulated same day as normal but my luteal phase is usually only 11-12 days. i had cramping on 4dpo and around 10 dpo but not even a drop of blood. i thought my period was coming yesterday with the temp drop but now i don't know. i've been testing every day since 8 dpo and all negative. 😔😔😔
