I am on my 3rd period in 23 days. The first was December 19th and lasted 5 days. It was not very heavy and consistedd of all dark brown blood. Then I started again on December 30th. This one lasted 3 days and was brown stringy blood that was very light. One pad per day. Then I started again yesterday, January 10th. So far, it is fairly light. One pad a day with brown blood and a little red. I can't get into the doctor until Monday and I am stressing a bit. I am starting a new period every 11 days. Definitely not normal. I am 29, married, and not on birth control. Any ideas on what the cause could be?
