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.
When you menstruate, your body sheds the lining of the uterus (womb). Menstrual blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina (see how the menstrual cycle works below). Most menstrual periods last from 3 to 5 days.aving regular menstrual cycles is a sign that important parts of your body are working normally. The menstrual cycle provides important body chemicals, called hormones, to keep you healthy. It also prepares your body for pregnancy each month.
