Is this normal?

I would like to consult a physician: My menstrual cycle is consistently about 30 days, but my period lasts around 10 days (which seems long).
We are planning to conceive, and after having intercourse with my husband a week after my period, I experienced bleeding.
In the past, when I had bleeding that was not part of my menstrual cycle, the blood was always brown, but this time it was bright red.
Is this normal? (I had a Pap smear and ultrasound four months ago, both of which were normal.)

More Info

When it comes to understanding menstrual cycles and unusual bleeding patterns, it's essential to consider various factors, including hormonal fluctuations, the timing of ovulation, and potential underlying health issues. Based on your description, it seems you have a regular menstrual cycle of about 30 days, which is generally considered normal. However, the duration of your periods lasting around 10 days may be on the longer side, as typical menstrual bleeding lasts between 3 to 7 days.

The occurrence of bleeding after intercourse, especially if it happens a week after your period, can be concerning and warrants further investigation. The fact that you experienced bright red bleeding, as opposed to the usual brownish discharge you mentioned, could indicate several possibilities. Bright red blood often signifies fresh bleeding, which can occur due to various reasons, including:
1. Ovulation Bleeding: Some women experience light spotting during ovulation, which can occur around the midpoint of their cycle. This is typically light and may be accompanied by other ovulation symptoms.

2. Cervical Irritation: Sexual intercourse can sometimes cause minor trauma to the cervix, leading to light bleeding. This is usually not a cause for concern if the bleeding is minimal and resolves quickly.

3. Hormonal Imbalances: Fluctuations in hormone levels can lead to unexpected bleeding. Stress, changes in weight, or significant lifestyle changes can impact hormone levels and menstrual regularity.

4. Polyps or Fibroids: These benign growths in the uterus can cause irregular bleeding. While you mentioned that previous tests were normal, it's worth noting that these conditions can sometimes develop over time.

5. Infections: Certain infections, such as sexually transmitted infections (STIs) or pelvic inflammatory disease (PID), can cause abnormal bleeding. If you have any accompanying symptoms like unusual discharge, pain, or fever, it's essential to seek medical attention.

Given that you had a Pap smear and ultrasound four months ago with normal results, it’s reassuring, but it does not completely rule out the possibility of new developments. If the bleeding persists, increases in volume, or is accompanied by other symptoms (such as pain or fever), it is crucial to consult with a healthcare provider for further evaluation. They may recommend additional tests, such as a repeat ultrasound or blood tests to check hormone levels.

In summary, while your menstrual cycle appears to be regular, the occurrence of bright red bleeding after intercourse is something that should be monitored. If it continues or you have concerns, do not hesitate to reach out to your healthcare provider for personalized advice and potential further investigation. Understanding your body and its signals is vital, especially when planning for a pregnancy.
