Does it mean that it has flowed out?


On October 15, I had unprotected intercourse with my boyfriend, and I was expecting my menstrual period on October 25, but it didn't come.
I took several pregnancy tests in between, and the lines were faint.
I experienced fatigue and abdominal pain, and by October 31, I also had lower back pain, which felt different from the previous abdominal pain.
That evening, I visited a gynecologist for a urine test, and the doctor said I wasn't pregnant, but an ultrasound showed a small dot, and I was advised to return the following week.
On the morning of November 1, I felt something was off, and when I went to the bathroom, I suddenly started bleeding, which felt just like my menstrual period.
Does this mean...

When it comes to distinguishing between a miscarriage and a late period, it's essential to consider various factors, including the timing of your symptoms, the nature of the bleeding, and any accompanying signs. Based on your description, it appears that you had unprotected intercourse on October 15, with an expected menstrual period (MC) on October 25, which did not arrive. You mentioned taking several pregnancy tests that showed faint lines, indicating a possible early pregnancy.
The symptoms you experienced, such as fatigue and abdominal pain, can be common in early pregnancy but can also occur with premenstrual syndrome (PMS). The key difference lies in the nature of the bleeding you experienced on November 1. If the bleeding was similar to your typical menstrual flow, it might suggest that your period has finally arrived. However, if the bleeding was heavier than usual, accompanied by severe cramping, or if you passed any tissue, these could be signs of a miscarriage.

In your case, the ultrasound showing a "small dot" could indicate a gestational sac, which is an early sign of pregnancy. However, the fact that the doctor later stated you were not pregnant after a urine test raises questions. It's possible that you were experiencing a chemical pregnancy, where a fertilized egg implants but does not develop properly, leading to an early miscarriage that can sometimes be mistaken for a late period.

It's crucial to monitor your symptoms closely. If the bleeding continues or worsens, or if you experience severe pain, it is advisable to seek medical attention immediately. Additionally, if you have any concerns about your reproductive health or future pregnancies, consulting with a healthcare provider or a gynecologist can provide you with the necessary guidance and support.

In summary, while your symptoms could indicate either a late period or a miscarriage, the specifics of your bleeding and the results of your medical evaluations will provide the best clues. If you're uncertain or if your symptoms change, don't hesitate to reach out to a healthcare professional for further evaluation. They can perform more definitive tests, such as blood tests to measure hormone levels, which can help clarify your situation. Remember, your health and peace of mind are paramount, so seeking professional advice is always a wise choice.
