When is it time to see a doctor?

The last couple of months my period cramps have been worsening to the point where i can't leave my bed. Last month it took a break and only crippled me for a day. But now its back to killing me. And with it it brought some friends; diarrhea and hot flashes. Last night at around 4am I woke up sweating and it terrible pain. I was crying and squeezing my stomach for almost an hour. Every time I tried to go back to sleep my body refused. I got hot then cold. I was freezing but sweating. My pain was past 10 on the scale. Should I see a doctor about this or am I just over reacting? I'm on my second day. I am really not looking forward to the rest of the week.
