There are actually quite a lot of reasons why your car insurance rates may rise. But your agent may have neglected to inform you of these reasons when you first signed up, or you may have forgotten them over the years.
Your body gets rid of the mucus plug typically between 37 and 42 weeks of gestation. It can even happen as late as right before delivery! Some women though can lose it earlier in the pregnancy, and again, the body will create more mucus to protect your baby.
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.
