Kristy,
Can your partner take time off around your due date? Im sure that will ease your mind a little. If this is your first pregnancy, it may last for hours and hours, so dont stress too much. Take warm baths, maybe do some relaxation.... make sure your DP has his mobile on him at ALL TIMES.. Your baby girl should start slowing her movements down a little, or you will get some type of "sign" before/as you go into labour so PLEASE stop stressing it will all be fine.
