Labor or Braxton hicks?! HELP!!

El
so i'm 37 weeks today & for about 2.5 hours my baby has been moving a ton. (he usually only moves a lot for a half hour to fortyfive minutes, so this is unusual for him to move soooo much) and i've been having painful menstrul like cramps in my upper & lower abdomen and lower back. i also have some pressure and can feel when baby moves right in my vagina. 
do you think these are braxton hicks contractions or real ones?! i have an appt in the morning, should i just wait or should i call the doctor now??
