Don't listen to everyone else's horror stories about labour because they won't happen to you. Everyone has a different experience during labour (the last baby my sister has was delivered in less than 2 hours ) The best thing you can do to prepare for labour is to get regular physical exerice (it makes the recovery alot easier) and take a birthing class.

From what you are describing you are experiencing what almost every other woman goes through at sometime during her pregnancy. You will be a great mom
