I'm 34 years old. For a very long time I had either no period or a really light period once a month. Now for the past 5 months they've been coming closer and closer together. It started out every two weeks, and now I'm getting a period every ten days or so. What gives? I'm a little underweight and have been anemic in the past but that's it. I'm going to see the Dr on monday, but I thought I'd see if anyone else has this problem?
