The best advice that you can try is to make sure you are really keeping up with your intake of water. You need to be drinking at a minimum of eight 8oz. Glasses a day if not more.
My wife's ob recommended that when she felt like she was going into labor, to drink 3 or 4 big glasses of water and lay on her left side for a while, most often false labor will be stopped and you will feel 100% better.
You are at a point where you can go at any time and you need to be sure when you begin labor that it is the real thing. Drink lots and let us know how you are doing,
