Menstrual issues?


My last menstrual period was from February 15 to February 20, but this time the flow is lighter than before.
On March 5, after using the restroom, I noticed some brown discharge, and in the morning of March 5, after wiping, there was some bright red blood.
What could be the cause of this? Is there a possibility of pregnancy (despite taking precautions)? Currently, I feel a lot of lower back pain and abdominal discomfort.

Hello, Wenzi: 1.
Please take a pregnancy test to check if you are pregnant.
2.
If you are not pregnant, it could be due to ovulation or pelvic inflammatory disease; please consult a doctor.

When it comes to understanding menstrual changes, several factors can contribute to variations in menstrual flow, including hormonal fluctuations, stress, changes in weight, and underlying medical conditions. In your case, the changes in your menstrual cycle, particularly the lighter flow and the presence of brown discharge followed by some fresh blood, could indicate a few possibilities.

Firstly, the brown discharge you observed is often old blood that has taken longer to exit the uterus, which can happen at the beginning or end of a menstrual period. It can also occur due to hormonal changes or fluctuations, especially if you have recently experienced stress or changes in your lifestyle. The fresh blood you noted could signify the start of a new menstrual cycle, but given the context of your previous period, it may also suggest other factors at play.

Regarding the possibility of pregnancy, while you mentioned that you have been using protection, no contraceptive method is 100% effective. If you suspect you might be pregnant, it would be advisable to take a home pregnancy test for confirmation. Early signs of pregnancy can sometimes mimic pre-menstrual symptoms, including abdominal discomfort and changes in menstrual flow.

The symptoms you are experiencing, such as lower back pain and abdominal discomfort, can also be attributed to various factors. These may include premenstrual syndrome (PMS), ovulation pain, or even early pregnancy symptoms. If you are experiencing significant discomfort or if your symptoms persist, it is essential to consult with a healthcare provider for a thorough evaluation.

In summary, while the changes in your menstrual cycle could be attributed to several benign factors, the possibility of pregnancy should not be ruled out entirely, especially given the changes you are observing. If you are concerned about your symptoms or if they worsen, seeking medical advice is crucial. A healthcare professional can provide a more accurate assessment and guide you on the next steps, including potential pregnancy testing or further investigation into your menstrual irregularities.
