Should I go to the doctor soon?

Kelsey
I'm a week and 2 days late. I feel bloated, I been having a horrible head ache, iv been very constipated, I have shortness of breath. And still no signs of my period. And I'm tired ALL the time!  
I have tested a few times but I'm still getting negatives. Should I go to the doctor or wait until the 2 full weeks of not having my period?
