Understanding abnormal menstrual patterns and their causes is crucial for women's health, especially as they approach menopause. Let's break down your questions and concerns systematically.

1. Irregular Menstrual Flow: You mentioned experiencing a normal cycle of 5-7 days, but sometimes the first two days have very little flow, followed by a sudden increase in bleeding with clots on the third day, and then a decrease again. This pattern can be concerning, especially as you approach menopause. It is not uncommon for women nearing menopause to experience changes in their menstrual cycle due to hormonal fluctuations. These fluctuations can lead to variations in flow, including heavy bleeding on certain days and lighter flow on others. However, the presence of blood clots and significant changes in your menstrual pattern should be evaluated by a healthcare provider to rule out conditions such as uterine fibroids, polyps, or endometrial hyperplasia.

2. Impact of Intrauterine Devices (IUDs): The use of an IUD can indeed affect menstrual patterns. Many women experience changes in their menstrual flow after getting an IUD, especially if it is a hormonal IUD. Some may experience lighter periods or even amenorrhea (absence of menstruation), while others may have increased bleeding or spotting. If you have concerns about how your IUD is affecting your cycle, it is advisable to discuss this with your healthcare provider.

3. Menstrual Odor: You noted experiencing a fishy odor during your period. This is not typical and may indicate an infection, such as bacterial vaginosis or a sexually transmitted infection (STI). It is essential to consult with a healthcare provider if you notice any unusual odors, especially if accompanied by other symptoms like itching or unusual discharge.

4. Localized Bleeding and Urinary Symptoms: You mentioned that during lighter flow days, blood tends to concentrate at the front of the pad, near the urethra, without any other urinary symptoms. While this may not be directly indicative of ovarian issues, it could suggest that the menstrual flow is being affected by the position of the pad or the way the blood is being expelled. However, if you experience any urinary symptoms such as pain, blood in urine, or increased frequency, it is crucial to seek medical evaluation to rule out urinary tract infections or other underlying conditions.

5. Post-Intercourse Odor: The presence of foul-smelling discharge after intercourse can be concerning. This could be due to several factors, including infections, changes in vaginal flora, or even retained menstrual products. If this odor is persistent or accompanied by other symptoms such as irritation, itching, or unusual discharge, it is important to consult with a healthcare provider for an accurate diagnosis and appropriate treatment.

In summary, while some changes in menstrual patterns can be attributed to hormonal fluctuations associated with approaching menopause, it is essential to monitor your symptoms closely. Any significant changes, especially those accompanied by unusual odors, pain, or other concerning symptoms, warrant a thorough evaluation by a healthcare professional. Regular gynecological check-ups can help in early detection and management of potential issues, ensuring your reproductive health remains a priority as you transition through different life stages.
