For the last two month I have had my period and then a week after I get off another one starts. What could be the reason for this? Please help

How long has this been happening? How old are you? Could you be peri-menopausal? Sometimes that happens Maybe you should have your hormone levels checked. Good luck.

I am 28 years old and It has been happening for the last two months. And I don't think that I am peri-menopausal at such a young age.

Possibly. It happened to my sister at 30. Maybe a little fibroid or just anxiety? Better to check with your dr.
