Been having contractions on and off for like 3 or 4 hours. Naseua(sp?) has been killing me. Super bad back pain. Can barely walk. Hurts to walk. Pain from my ribs down to my abdomen. I was almost in tears earlier. Debating on whether or not to go to labor&delivery;. Not sure what to do 😩 I'm 36 weeks, btw
