Parkinson disease is a progressive disorder of the nervous system. The disorder affects several regions of the brain, especially an area called the substantia nigra that controls balance and movement. Often the first symptom of Parkinson disease is trembling or shaking (tremor) of a limb, especially when the body is at rest. Typically, the tremor begins on one side of the body, usually in one hand. Tremors can also affect the arms, legs, feet, and face.
It might be heavy but short. It might only be spotting. A short period might mean you're pregnant. These can all be signs of a pregnancy. The only way to sort out the pregnancy from the rest of the reasons would be to take a pregnancy test. Sometimes what a woman mistakes for her period is really what we call implantation bleeding, a slight bleeding that occurs and the baby implants into your uterus.
If you've been having periods for 2 years or less and your physical exam is normal, your irregular periods may be part of your normal development. Remember, if you have had sex, go to your doctor's office for a pregnancy test when your period is late for you, even if you normally have irregular cycles.enstrual flow lasts about 3 to 7 days. A menstrual period is considered late if it is 5 or more days overdue according to your usual pattern of periods. A period is considered missed if there is no menstrual flow for 6 or more weeks.
