Guys I'm losing my damn mind here

Sarah

AF has officially been missed, I've never missed a period in my 17 years if having a period. I've had brown/rust spotting for 3 days. I can find it with a Cervical check, but not even a drop on a panty liner! Negative test this morning with FMU, I'm so confused. My chart is absurd this month too. Help! I'll post chart and most recent test in comments.
