Period 3 days late

I took 2 pregnancy tests 4 days ago though and both came out negative. Also I had light pink spotting some before my period was due but I can’t remember exactly when. Is it possible? I’ve been waiting for so long it feels like it can’t be. Should I take another pregnancy test or should I just take the first tests as accurate and wait?

Update: 4 days late

Took a clear blue test today. Said not pregnant. But my period is still nowhere to be seen. I’m 33 dpo
