Back, Hip, and Breast Pain

I am a 26 year old female. I usually get a small dose of lower back pain when i am on my period. This round however started weird. First my breast started hurting a lot sooner then they normally do when getting close to time for my period. They hurt for close to 2 weeks instead of the normal half of a week until the period starts. Well with how it was hurting this time i thought i might be pregnant. Especially since the veins in my breast were a little more visible then normal. Then i got my period about 2 days ago.. its be a rather heavy period even for me and today my lower back started hurting worse then it normally does. I'm having trouble getting up from laying on my stomach and even taking certain steps or going up stairs is a challenge.. the pain i am feeling is a lot like a really bad kidney infection across my lower back and somewhat in my hips.. does anyone know what could be going on?
