I need to know if I should be worried about this. I am a 28 yr old white female. I am considerably overweight, but I have not had a menstrual cycle in about 50 days. I counted back from the last day of my cycle and its been that long. I haven't ever been regular as far as starting on the same date each month but never more than a few days later than the date the previous month. This may not be enough information but I hope you can help me.
