Extreme period pains

So my period started today, and as always, this cycle has brought more pain with it than the last. This time, I have been having pains from my lower stomach, to my hips, down my legs. The down my leg pains come and go, but the stomach and hip pains have been consistent throughout the day. My lower back has been hurting quite a lot as well, and I've felt rather lightheaded/dizzy and nauseous all day. Surprisingly, I haven't had a headache yet like I normally do, but my flow is heavier than the time before this. 
I'm 17, is this kind of pain normal? I'm on no kind of birth control, but I've taken 4 Midol today with no relief. At this point, is there anything else can I try to ease the symptoms?
