3 days late negative hpt

Ta

I'm 3 days late. Lmp 12/30. Got a negative hpt this morning but have been having sore breasts, bloating and today very VERY sensitive teeth out of the blue. We have been ttc for 4 months. Am I out for this month and af is just late for some reason? Or is it still possible that I could be pregnant even though I had a negative test this morning? 😥
