Missed period negative test

Dev

I am now 4 days late on my period. My cycles are an average of 32-33 days and my period has never been late. I tested the day after my period was due and then 2 days after that and I got both negative results. I’m thinking I might have ovulated later this cycle because my bbt dipped later than usual and my husband and I baby danced on that day.

Could I still be pregnant? Today is Day 38 of my cycle.
