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.
You should get your period about once every month. A typical menstrual cycle is about 28 days. This means that there should be about 28 days from the first day of your period to the first day of your next period. 28 days is an average number, but anywhere between 21 and 35 days is normal. In the first year you should have at least 4 periods, the second year at least 6 periods, and for the 3-5th year, at least 8 periods. Adults should have at least 9 periods a year. Your period will usually last between 3 and 7 days. The amount of blood flow you have will probably be different each day.
