Labor is a scary enough prospect--it gets even worse when you are waiting longer than you have to for it to start. There are several ways to start labor inducing and many reasons why you would want to. The most common reason is that the baby is overdue. If the baby is extremely overdue, you will want a doctor to medically induce you. However no inducement should be attempted without a doctor's permission.
Labor starts when your uterus muscles contract to push the baby out. If you can get other areas near your uterus to have contractions, it could stimulate the proper muscles to follow suit. These remedies are often natural, healthy ones, like taking Castor oil. It will make your digestive system contract.
Spicy food can do the same thing in the same type of way. Pregnant women tend to crave spicy food anyway. As long as a doctor says it is healthy diet-wise and healthy for the baby's birth, this can be a very pleasant way to get things started.
An enema is a gross, but effective, way to also stimulate the digestive tract. It makes sense, since so many excrete during labor due to the close proximity of vagina to anus--the contractions affect both areas. It is natural, therefore, that it would work the opposite way. Once again, you must be careful and get a doctor's permission.
Intercourse is the direction most people take. It directly stimulated the uterus muscles. Some women are self-conscious or uncomfortable with it at this late stage in the pregnancy, so breast stimulation may work just as well. One's nipples are directly connected to the uterus in a physiological way. Their especial sensitivity during pregnancy could cause uterine contractions if the nipples are stimulated enough.
Keep in mind that these are not fool-proof. You can try all of these to excess but they may just not work. What is important is the baby's safety and your own. You may have to suffer in discomfort for a few more days, or even weeks. As long as your doctor sees no problem with a continuing pregnancy and does not want to medically induce labor, you will be fine, if grumpy.
Labor inducing is not something that women look forward to, especially when it is done by medicines. However, you can induce labor naturally through acupressure. Visit http://www.helpinducelabor.com/
