Itchy skin, also known as pruritus, is an irritating and uncontrollable sensation that makes you want to scratch to relieve the feeling. The possible causes for itchiness range from internal illnesses, such as kidney or liver disease, to skin rashes, allergies, and dermatitis.
The menstrual cycle is not the same for every woman. On average, menstrual flow occurs every 28 days (with most women having cycles between 24 and 34 days), and lasts about 4-7 days. However, there is a wide variation in timing and duration that is still considered normal, especially if your periods began within the last few years. A small percentage of women have periods more often than every 21 days or less often than every 35 days. These variations may be normal. Often, if you are bleeding from the rectum or there is blood in your urine, you may think the blood is coming from the vagina.
Then, during your period, your body sheds the uterus lining along with blood. The amount of blood and fluid lost is usually between four and 12 teaspoons each cycle. The average menstrual cycle lasts 28 days. For some women, though, cycles can be as short as 21 days. For others, they can be as long as 35 days. A normal period lasts between two and seven days.
