shirley coppo answered question 12/15/2010 Last Month I Had My Period Twice, Two Weeks Apart. Now I Haven't Started My Period For This Month. What's Going On? I am 52 years old and still have my periods. But last month had one for 3 weeks. Then finally stop and I am having normal periods again, Heavy bleeding but only once a month I would like to know why did I have a 3 week period.
