Left lower abdominal pain and it feels slightly larger than the right lower abdomen?


During the ovulation period on July 2, I experienced alternating abdominal pain on both sides (with more pronounced sharp pain in the left lower abdomen), diarrhea, and brownish discharge with blood for one day.
The abdominal pain and the urge to have a bowel movement have persisted from the ovulation period until now (approximately 9 days).
I expect my period to start in 8 days, and in the past two days, I have particularly noticed that the left lower abdomen feels and looks slightly larger than the right lower abdomen.
Additionally, I have been experiencing a dull ache and cramping sensation near the left side of my navel and just below it.

1.
Is it normal to have asymmetrical abdominal size and unilateral pain before menstruation?
2.
Is the persistent pain due to ovulation pain, followed by premenstrual syndrome causing lower abdominal pain?

More Info


Understanding left lower abdominal pain before menstruation can be complex, as it involves various physiological and anatomical factors. Based on your description, it seems you are experiencing a combination of symptoms that may be related to ovulation, premenstrual syndrome (PMS), and possibly other underlying conditions.

1. Asymmetry in Abdominal Size and Pain: It is not uncommon for women to experience asymmetrical abdominal sensations or discomfort, particularly around the time of ovulation and menstruation. During the menstrual cycle, hormonal fluctuations can lead to changes in the size and sensitivity of the ovaries and surrounding tissues. The left ovary may be more active in some cycles, leading to increased pain or discomfort on that side. However, if you notice a significant difference in size or persistent swelling, it is essential to consult a healthcare provider to rule out any potential issues such as ovarian cysts or other abnormalities.

2. Persistent Pain and Its Causes: The pain you are experiencing could indeed be a combination of ovulation pain (also known as mittelschmerz) and premenstrual syndrome. Ovulation pain typically occurs mid-cycle and can last from a few minutes to a few hours, but in some cases, it can persist longer. Following ovulation, many women experience PMS, which can include symptoms such as abdominal cramping, bloating, and mood changes due to hormonal shifts. The combination of these two phases could explain the ongoing discomfort you are feeling.

Additionally, the presence of brownish discharge with blood could indicate that your body is preparing for menstruation, but it could also be a sign of other conditions, such as endometriosis or pelvic inflammatory disease (PID), especially if accompanied by significant pain or other unusual symptoms. Endometriosis, for instance, can cause chronic pelvic pain and may lead to asymmetrical pain or swelling in the abdomen.

Recommendations:
- Monitor Symptoms: Keep track of your symptoms, including the intensity and duration of the pain, any changes in discharge, and any other accompanying symptoms such as fever or unusual fatigue. This information can be valuable for your healthcare provider.

- Consult a Healthcare Provider: Given the duration of your symptoms and the asymmetry you’ve noticed, it would be wise to consult a healthcare provider. They may recommend a pelvic ultrasound or other imaging studies to assess the ovaries and surrounding structures for any abnormalities.

- Pain Management: Over-the-counter pain relief, such as NSAIDs (e.g., ibuprofen), can help manage discomfort. However, if the pain is severe or persistent, it’s crucial to seek medical advice rather than relying solely on medication.

In conclusion, while some degree of discomfort before menstruation can be normal, especially in relation to ovulation and PMS, persistent or severe pain warrants further investigation. It’s essential to prioritize your health and seek professional guidance to ensure that any underlying conditions are appropriately addressed.
