Why Do I Experience Abdominal Pain Before My Period?

Abdominal pain before your period is common and usually happens because your body is getting ready for your monthly cycle, which involves changes in hormones and the uterus.

Explanation

Many people feel belly pain before their period, and this is often caused by cramps. Your uterus starts to contract as it gets ready to shed its lining, and these contractions can hurt. This pain is called dysmenorrhea, and it is very common. Changes in hormones before your period can also affect other parts of your body, like your stomach and intestines, making them cramp too. This can sometimes be part of a mix of symptoms known as premenstrual syndrome (PMS). Sometimes, the pain is mild and goes away when your period starts. Other times, it might be more noticeable and uncomfortable. To help with the pain, you might try resting, using a warm heat pad on your lower belly, or doing gentle stretches or walks. If the pain is very strong every month, it is a good idea to talk with a healthcare provider for pain management recommendations and to determine whether additional testing might be needed.
