Terrible periods!

Emily
Im 17 and my periods never used to bother me this much but about 2 years ago they started getting really bad. I guess this runs in my family but is there anything I should be worried about or seeing a doctor for? All my symptoms happen the first day and hit me all at once. They are: 
​Severe backaches and cramping 
​Nausea
​Vomiting 
​Migraine
​Bloating
​Sensitivity to any smells
​Sensitivity to light
​Inability to concentrate
​Constipation
​Hot and cold flashes
​Shaking
 
​I always take Midol but it rarely helps. I have to leave work frequently when this happens. It's really annoying and embarrassing.  I'm not on birth control however I am sexually active. I just wanna know if this is normal or something I should get checked out.
