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.
Losing the mucus plug is just one thing that may indicate that labour has started, or will start soon. Others are the position of your baby and whether you've had a baby before. If this is your first baby, your labour may not start for another week or so after you lose the mucus plug. Or it could be a sign that you're in early labour. Early labour, where you may feel mild contractions, tummy aches, cramps or backache, can last for hours or days. On the other hand, if you've had a baby before, losing the mucus plug could be a sign that labour will start in earnest within hours. When the mucus plug dislodges from your cervix it's called the show, or a bloody show. The jelly-like plug is often blood-tinged or streaked with old, brownish blood when it comes away.
