I have had an irregular menstrual cycle since the onset of my menses at age 9. I am overweight so I have often had to diet, take birth control pills or other hormones to regulate my cycle (have a cycle every month) Usually my cycles are 3-5 days. For the past 9 months, my cycles have been monthly, for the last 2 months, they have been 7 days or more. I turned 43 in October and have never been able to calculate when my cycle will be. I have often skipped months at a time without hormones. Should I be concerned that I am having a cycle now without hormones monthly, and that they are much longer than usual. I am not experiencing any pain, heavy bleeding or side effects. The first week is more like spotting, the second week is the heaviest flow and has lasted 5 days before the spotting begins and it stops.
