I just read your previous post after posting my last message, and yes, your water can break at 20 weeks, I know because I delivered my daughter at 21 weeks and my water broke on it's own. I will be so mad if this is a joke, but if not, please contact me. I will help you in what ever way I can. Maybe you were just panicking, but next time (god forbid there is a next time), call the ambulance!
