Blah getting sick of this

Shelby-Rae
Well my period is a week late and I feel sick to my stomach and certain smells make me sick and my boobs hurt and are getting bigger and I can't get comfortable to go to sleep. I have taken 3 tests and they came back negative so I decided to see a doctor they only did a pee test and refused to do a blood test. My period is never late. Please help
