Could today be the day?

I honestly hate posting things like this here, but everytime I ask my family if something is "normal" they tell me the same thing.

Anyway I'm 39weeks 5 days. It's 6am here and I barely slept at all last night. I had cramping-intense enough to keep me up throughout the night- along with my back feeling like its constantly cramped. I have had a headache for the past hour. My pelvic area/hips feel like someone is pulling them apart and it hurts so bad. I can barely stand up or walk and when I do it hurts even worse :( Now I'm staying to feel sick to my stomach :( Yesterday and the day before I felt great(before that I was depressed and sad all day long and cried half the day) I had slept so well and cleaned my car out and did some other cleaning.

I don't want to get my hopes up that maybe Ill be meeting my baby if I probably won't. My next dr appt is Wednesday(at 40weeks)

EDITED TO ADD - I just threw up :(
