No period but negative test?

Sierra

Hello! I need some advice, opinions, something! My period is 4 days late but I have had 3 negative pregnancy tests :( I took one yesterday morning, 5 days ago, and a week before my period was due. I’m having a ton of early pregnancy symptoms such as bloating, nausea, fatigue and increased appetite. Could I still be pregnant? Or am I just wishful thinking?

Help!
