Changes in the menstrual cycle can be concerning, especially when there is a significant alteration in the frequency and duration of periods. In your case, you mentioned that your menstrual cycle has shortened from a regular 26-28 days to approximately 20 days over the past six months, with each period lasting about seven days. This change can be attributed to several factors, and understanding these can help in managing your symptoms effectively.

Firstly, hormonal fluctuations are one of the most common reasons for changes in the menstrual cycle. The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. Any imbalance in these hormones can lead to irregularities. Factors that can influence hormonal balance include stress, significant weight changes (either gain or loss), excessive exercise, and underlying health conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.
Stress, in particular, can have a profound impact on your menstrual cycle. When the body is under stress, it can lead to increased levels of cortisol, which may disrupt the normal hormonal balance and affect the timing of ovulation. If you have been experiencing increased stress in your life, it might be worth considering stress management techniques such as mindfulness, yoga, or counseling.

Another potential cause for the changes in your cycle could be related to age and the natural transition towards perimenopause, especially if you are in your late 30s or early 40s. During this time, hormonal fluctuations can lead to changes in the menstrual cycle, including shorter cycles and variations in flow.

Regarding the issue of prolonged bleeding or spotting after your period, this could be related to the uterine contractions you mentioned. If your doctor suggested that your uterus has poor contraction strength, it could lead to prolonged bleeding or spotting. This condition can be influenced by hormonal levels, uterine health, or even the presence of fibroids or polyps.
To address these concerns, it is essential to consult with a healthcare provider who can perform a thorough evaluation. This may include blood tests to check hormone levels, an ultrasound to assess the health of the uterus, and possibly other diagnostic tests to rule out any underlying conditions.
In terms of treatment, if hormonal imbalances are identified, your doctor may recommend hormonal therapies, such as birth control pills, to help regulate your cycle. If there are structural issues within the uterus, such as fibroids or polyps, surgical options may be considered.

Additionally, lifestyle modifications can also play a significant role in managing menstrual health. Maintaining a balanced diet, regular exercise, and managing stress can help improve overall hormonal balance and menstrual regularity.
In summary, the changes in your menstrual cycle could be due to various factors, including hormonal imbalances, stress, age-related changes, or uterine health issues. It is crucial to work closely with your healthcare provider to identify the underlying cause and develop an appropriate treatment plan tailored to your needs. Regular follow-ups and open communication with your doctor will be key in managing your menstrual health effectively.
