Symptoms can occur a bit differently in each teen. The most common symptoms include:
- Cramping and pain in the lower abdomen.
- Low back pain.
- Pain spreading down the legs.
Other symptoms can include:
- Nausea.
- Vomiting.
- Diarrhea.
- Tiredness.
- Weakness.
- Fainting.
- Headaches.
Symptoms occur just before menstrual bleeding starts each month. The pain can last for 1 to 2 days or more. It then lessens at the end of the period.
Symptoms of secondary menstrual cramps can start several days before menstrual bleeding starts. The pain may get worse and last for days, weeks, or longer.
Menstrual symptoms can be like other health conditions. Make sure your teen sees their doctor for a diagnosis.
