Missed period, neg…

Just looking to see if any of y’all have had this happen and if so, what does it mean/steps forward/thoughts?!

My period has been within 24hrs of my tracking day for over the last year (honestly didn’t track well before then so I’ll just say the year I’ve been tracking). I was due Monday. Still no flow, took a test Tuesday, negative. As of today, still no flow but minor cramping, sore boobs, bloating/gas, etc. everything I’m reading is saying the test was likely correct (took day after missed period, took in morning) sooo… wtf? No new meds, no change in stress (high stress career but not new)… thoughts? Ty :)
