am I close?

How did everyone feel before going into labor? 38+3 and have been having a very "off" day .. Usually I sleep perfectly all night, but I could not sleep at all last night, now my stomach feels very weak as if I had a bug, and hurts sort of like after you throw up a lot and your stomach is sore ..  I have a stuffed nose and I feel very weak all together and a really down feeling but nothing is wrong? Could this mean I'm close? Or just a bad day
