6 days late.. negative tests (urine & blood)

Hey ladies. So i’ve been on BC for 2 years and have always had regular periods. I’m now for the first time 6 days late and have had symptoms like lower back pains, headaches, fatigue and tired like crazy, cramps and etc. I’ve had negative tests but just don’t know if it’s too early or not. Anyone else have this issue?? Planning on going to Dr. on wednesday
