I am a midwife. Losing your plug does not mean you are in labor. Also the plug will regenerate itself after 24 hours. Labor is when the contractions get longer in duration, increase in intensity and the duration between each one shortens. It sounds like you have what is called an irritable uterus. Drink a glass of wine and take a warm bath. The wine will relax the uterus which is just a big muscle. This is perfectly safe. We tell women to do this all the time.
