Menstrual Cramps: Causes and Concerns Before Your Period

Menstrual issues

Hello doctor, I would like to ask about something.
Sometimes before my period, if I go for a run, I experience a dull pain in my lower abdomen that feels similar to menstrual cramps.
The pain seems to increase as my period approaches.
Is this normal? What could be the reason for this? For instance, my last period started on August 18, and I was expecting it to start today, but it hasn't come yet; I've only noticed some discharge.
I went for a run this afternoon, and my stomach feels similar to before, with pain.
Could this be a sign that my period is coming soon?

Before menstruation, if running causes a dull pain in the lower abdomen similar to menstrual cramps, and the pain may increase as menstruation approaches, is this normal? What could be the reason? Answer: An ultrasound examination is necessary.
For example, if the last menstruation started on August 18 and it was expected to start today but has not yet appeared, only discharge is present.
After running in the afternoon, the abdomen also experienced pain similar to before.
Is this because menstruation is approaching? Answer: It is possible.

More Info

Menstrual cramps, also known as dysmenorrhea, are a common experience for many individuals during their menstrual cycle. They can manifest as a dull ache or sharp pain in the lower abdomen, and they often intensify as the period approaches. Your experience of feeling discomfort or cramping in your lower abdomen after running, especially as your period nears, is not uncommon and can be attributed to several physiological factors.

One of the primary causes of menstrual cramps is the release of prostaglandins, which are hormone-like substances that help the uterus contract to shed its lining during menstruation. Higher levels of prostaglandins are associated with more intense cramps. When you engage in physical activity, such as running, your body may respond with increased blood flow and muscle contractions, which can exacerbate the sensation of cramping, particularly if your period is imminent.

Additionally, the hormonal fluctuations that occur in the menstrual cycle can lead to various symptoms, including bloating, mood swings, and abdominal discomfort. As you approach your period, your body prepares for menstruation, which can lead to increased sensitivity in the pelvic area. This sensitivity can make you more aware of any discomfort, especially after physical exertion.

Regarding your concern about the timing of your period, it is important to note that menstrual cycles can vary in length and regularity due to numerous factors, including stress, changes in physical activity, diet, and overall health. If your last period started on August 18 and you expected it to arrive today but have only experienced discharge, it could be a sign that your cycle is slightly delayed. This delay can be influenced by various factors, including hormonal changes or lifestyle adjustments, such as increased exercise.

If you are experiencing significant pain or if your menstrual cycle becomes irregular, it may be beneficial to consult with a healthcare provider. They can help determine if there are any underlying conditions, such as endometriosis or fibroids, that could be contributing to your symptoms. Additionally, they can provide guidance on managing menstrual cramps, which may include lifestyle modifications, over-the-counter pain relief, or hormonal treatments.

In summary, the discomfort you experience before your period, especially after running, is likely a normal response to the hormonal changes in your body and the physical activity you engage in. However, if you have concerns about the severity of your cramps or the regularity of your menstrual cycle, seeking medical advice is always a prudent step. Your health and well-being are paramount, and a healthcare professional can provide personalized recommendations based on your specific situation.
