Abdominal Bruising and Irregular Bleeding After Impact

Lower abdomen impact?

Hello, doctor.
Two days ago, I bumped my lower abdomen (on the left side) against a blackboard, and a day later, I noticed a purple bruise about the size of three fifty-cent coins.
On the same day, I experienced bleeding similar to my menstrual period (which is about a week earlier than expected based on my ovulation cycle), but there was bleeding only that day.
The next day, there was almost no blood on the pad.
Could this be due to the impact? Why was there no further bleeding afterward? Thank you.

More Info

It sounds like you experienced a significant impact to your lower abdomen, which resulted in bruising and some irregular bleeding. Based on your description, it is possible that the bruising (the purple mark you observed) is a result of the trauma from the impact. Bruising occurs when small blood vessels break under the skin, allowing blood to leak into the surrounding tissue, which can create the discoloration you see.

The irregular bleeding you experienced could also be related to the impact. Trauma to the abdomen can sometimes affect the reproductive organs, especially in women, leading to changes in menstrual bleeding patterns. The timing of your bleeding, being close to your expected menstrual period, might suggest that the impact could have coincided with your menstrual cycle, potentially causing a disruption. However, it is also possible that the bleeding was a result of the trauma itself, which could have caused a temporary disturbance in your hormonal balance or affected the lining of the uterus.

The fact that the bleeding stopped after one day is not uncommon. In many cases, minor trauma can lead to a brief episode of bleeding, which may resolve quickly as the body begins to heal. If the bleeding was due to the impact, your body may have absorbed any small amount of blood that was released, leading to the cessation of bleeding.

However, it is important to monitor your symptoms closely. If you experience any of the following, you should seek medical attention promptly:
1. Severe abdominal pain: If the pain worsens or becomes severe, it could indicate a more serious injury.

2. Persistent or heavy bleeding: If you notice an increase in bleeding or if it becomes heavy, this could be a sign of a more significant issue.

3. Dizziness or fainting: These symptoms could indicate internal bleeding or a drop in blood pressure.

4. Changes in bowel or urinary habits: If you experience any changes in your bowel movements or urination, this could suggest an injury to the organs in the abdomen.

In terms of treatment, if the bruising and bleeding are mild and you are not experiencing any alarming symptoms, it may be sufficient to rest, apply ice to the bruised area, and monitor your condition. Over-the-counter pain relief, such as acetaminophen or ibuprofen, can help manage any discomfort.

If you have any concerns about your symptoms or if they worsen, it is advisable to consult a healthcare professional. They may recommend imaging studies, such as an ultrasound, to assess for any internal injuries or complications resulting from the impact.
In summary, while the bruising and irregular bleeding you experienced could be related to the impact, it is essential to keep an eye on your symptoms and seek medical advice if anything concerning arises. Your health and safety should always be the priority.
