Periods & Fevers

So my period ended last week (as it should have) but this week I had a really bad fever to the point where I'm still on the mend. (I don't get sick very often but when I do, I'm out of commission for a while). Anyway, my period started back up again but it's not like my normal flow. It's heavy, I'm getting serious pelvic pain, back pain and side pain. I can't eat or drink anything in fear of my stomach trying to murder me and I haven't been able to sleep for more than a couple hours at a time. I'm always in the bathroom or lying down in bed. So I guess what I'm trying to ask is, is this normal?
