4 days late, all tests negative

Hi ☺️

We have been trying for almost a year. Had a missed MC in early November at 13 weeks.

My period is 4 days late, and it has NEVER been before, besides when i got pregnant with my rainbow baby 🌈

Took tests the last three days, but all negative. What could this mean? Can i still be pregnant? I feel no symptoms of period arriving like i normally do.
