Pregnancy: If you had regular cycles before and are having this abnormal bleeding now, you could be pregnant. A pregnancy test can confirm this easily. Still, it's common for young women to miss a cycle on occasion. It's more common if you are athletic, lose or gain weight over a short time, or taking some medications. I would monitor the symptoms and contact your doctor if it persists.
