What if your menstrual cycle lasted for more than 14 days?
If you mean you were bleeding for more than 14 days, I would go see a doctor. If you meant your entire cycle was more than 14 days, that's normal. It should be around 28 days. Hope this helps answer your question. If you are still unsure, resubmit your question with more detail. Or call a doctor, they'll have more answers for you.
