Intercourse-related bleeding

Hello, I have not fully recovered from a bacterial infection, and my period is about a week late.
During intercourse, I experienced a small amount of bright red bleeding, which stopped by the evening.
Initially, my partner thought it was my period, so he ejaculated inside me.
I took emergency contraception at the beginning of the month.
Given this situation, should I take emergency contraception again?

Hello:
1.
Post-coital bleeding may have several possible causes:
(1) Excessive force may cause tearing of the hymen or vaginal wall.

(2) Cervical erosion or rupture of fragile microvessels can lead to bleeding.
Causes may include infections or abnormal cervical cells.

(3) Shedding of the endometrium can result in bleeding, which can occur in individuals using intrauterine devices (IUDs), or those with poor ovarian function or insufficient hormone secretion.

2.
If you took emergency contraception at the beginning of January and it has been 2 to 3 cycles since, it is advisable to take it again if needed.

Thank you for your message!

More Info

Post-intercourse bleeding can be concerning and may arise from various causes. It is essential to understand the potential reasons behind this bleeding and what steps to take next.

Firstly, it is important to note that post-intercourse bleeding can occur due to several factors, including:
1. Cervical or Vaginal Irritation: If there is any irritation or inflammation in the vaginal or cervical area, it can lead to bleeding during or after intercourse. This could be due to infections, such as bacterial vaginosis or sexually transmitted infections (STIs), which you mentioned you are still recovering from.

2. Hormonal Changes: Hormonal fluctuations can also cause changes in the vaginal lining, making it more susceptible to bleeding. This is particularly relevant if you are close to your menstrual cycle.

3. Cervical Polyps or Fibroids: Non-cancerous growths on the cervix or within the uterus can cause bleeding during or after sexual activity. These are usually benign but should be evaluated by a healthcare provider.

4. Infections: As you mentioned having a bacterial infection, it is crucial to ensure that it has been adequately treated. Infections can lead to inflammation and bleeding.

5. Trauma: Sometimes, vigorous sexual activity can cause minor trauma to the vaginal walls or cervix, leading to bleeding.

Given your situation, where you experienced bleeding after sexual intercourse and have a history of a bacterial infection, it is advisable to take the following steps:
- Consult a Healthcare Provider: Since you are experiencing post-intercourse bleeding, it is essential to consult with a healthcare provider, preferably a gynecologist. They can perform a thorough examination, including a pelvic exam, to determine the cause of the bleeding.

- Follow-Up on Infection Treatment: If you have been diagnosed with a bacterial infection, ensure that you complete the prescribed course of antibiotics or any other treatment. If symptoms persist, inform your healthcare provider, as you may need further evaluation or a different treatment approach.

- Monitor Symptoms: Keep track of any additional symptoms you may experience, such as pain, unusual discharge, or changes in your menstrual cycle. This information will be helpful for your healthcare provider.

- Avoid Sexual Activity if Necessary: If you notice bleeding or discomfort during or after intercourse, it may be wise to refrain from sexual activity until you have consulted with a healthcare provider. This can help prevent further irritation or injury.

- Consider Contraceptive Options: If you are concerned about the possibility of pregnancy, especially since you mentioned internal ejaculation, consider discussing contraceptive options with your healthcare provider. They can guide you on the best methods to prevent unintended pregnancy and protect against STIs.

In summary, post-intercourse bleeding can have various causes, and it is crucial to seek medical advice to determine the underlying issue. Proper diagnosis and treatment are essential to ensure your health and well-being. Do not hesitate to reach out to a healthcare professional for guidance and support.
