Is it possible I’m pregnant ?

I am on cd 30. My cycle is usually 26-28 days so I’m officially 2 days late. I have been having pregnancy symptoms since Friday; incredibly sore and tender breast, tightness/mild cramping really low on stomach (a lot lower than I usually get it), bad nausea, very congested, and emotional for no reason. I don’t normally get any of these symptoms before my period and each day since Friday it’s been getting progressively worse. I took a test this morning and it’s negative. I don’t track my ovulation but the app says it was on the 26th of February so it was sometime around then. I am never late, mg cycle is like clockwork. Could I be pregnant and it was just too early? Should I test again?
