Dendritic drainage In geomorphology , drainage systems , also known as river systems , are the patterns formed by the streams , rivers , and lakes in a particular drainage basin . They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.
Loss of the mucous plug means that labor will most likely start within the next 2 to 3 weeks, sometimes sooner, but that is the norm. If you are less then 36 to 37 weeks you need to inform your Dr. or Midwife if you lose your plug, as this could be a sign of an early delivery.
When this happens, the mucous plug is no longer large enough to fill the opening and it eventually comes out. It may come out all at once, or it may come out slowly in the vaginal discharge over a couple of days. Losing the mucous plug is a sign your body is starting to prepare for labor. You may lose your plug as early as one to two weeks before the true signs of labor appear, or just as labor itself is beginning.
