STD Risks and Testing After Unprotected Sex

Sexually Transmitted Infection Inquiry

This month, I had unprotected sexual intercourse with different partners three times (they indicated they have no history of sexually transmitted infections).
The dates were 10/5, 10/13, and 10/16.
After the first encounter, I experienced a cottage cheese-like white discharge from the vagina (internet research suggested it might be a yeast infection), which lasted from 10/9 to around 10/12, and then the symptoms resolved, indicating it likely healed.
During the second encounter, I experienced some discomfort and minor wounds in the perineal area.
The third encounter was normal.
Today marks the 16th day since the first unprotected intercourse, the 8th day since the second, and the 6th day since the third.
After 10/11, I developed some discomfort symptoms: headaches (I can feel a lump at the back of my head), nausea (which I had experienced before my period), and diarrhea (possibly due to eating too much grapefruit—two a day during the Double Tenth holiday).
On 10/10, I noticed swelling of the lymph nodes on the right side of my neck and slight pain in my right ear (I did not seek medical attention).
Today, 10/20, is the first day of my period, and I still have headaches (in the temples and around the temples) and nausea (I haven't actually vomited, just feeling nauseous and having a gag reflex), along with some throat pain and dryness (the lymph nodes are not noticeably swollen).
I have purchased testing kits from the Ministry of Health and Welfare (I bought them today, and they haven't arrived yet).
Do I have any sexually transmitted infection-related issues? (I know I've been reckless this month, and I deeply regret it).
What should I prepare for? Should I get tested at a major hospital in three months? How many times do I need to be tested? Is the self-testing from the Ministry of Health and Welfare effective or accurate? (They said I can self-test between 23-90 days, and I bought two kits).

It is indeed necessary to rule out HIV infection.
Self-testing has a high accuracy rate, but if there are any concerns, one can still seek medical attention for a blood test.

Engaging in unprotected sex can significantly increase the risk of sexually transmitted diseases (STDs), including HIV. Given your recent experiences, it's crucial to understand the risks involved and the appropriate steps to take for testing and prevention.

Firstly, you mentioned having unprotected sex three times within a short period. Each encounter carries its own risk, especially if any of the partners had an undiagnosed STD. The symptoms you experienced, such as the white discharge, could indicate a yeast infection, which is not an STD but can occur after sexual activity. However, the presence of symptoms like headaches, nausea, diarrhea, and swollen lymph nodes raises concerns about potential infections, including STDs.

When it comes to testing for STDs, the general recommendation is to wait for a window period before getting tested. For HIV, the window period can vary depending on the type of test used. Most modern tests can detect HIV within 10 to 14 days after exposure, but for conclusive results, testing at 3 months is often advised. This is because some infections may not be detectable immediately after exposure due to the body's immune response.

In your case, since you are already 16 days post the first encounter, it would be wise to get tested for STDs, including HIV, as soon as possible. You should also consider retesting at the 3-month mark to ensure that any potential infections are detected. The self-testing kits you purchased can be useful, but it's essential to follow the instructions carefully and understand that while they can provide preliminary results, they may not be as comprehensive as tests conducted in a medical facility.

Regarding your symptoms, particularly the swollen lymph nodes and persistent headaches, it would be prudent to consult a healthcare provider. These symptoms could be indicative of an infection that requires medical attention. Additionally, if you have any open wounds or sores, they could increase the risk of transmitting or contracting STDs.

As for communication with your sexual partners, it's important to inform them of your situation, especially if you test positive for any STDs. This is not only a matter of personal responsibility but also essential for public health. Encouraging your partners to get tested can help prevent the spread of infections.

In summary, here are the steps you should take:
1. Get Tested: Seek testing for STDs, including HIV, as soon as possible. Follow up with additional testing at the 3-month mark for conclusive results.

2. Consult a Healthcare Provider: Given your symptoms, it’s advisable to see a doctor for a thorough evaluation and possible treatment.

3. Communicate with Partners: Inform any recent sexual partners about your situation so they can also seek testing.

4. Practice Safe Sex: Moving forward, consider using condoms consistently to reduce the risk of STDs.

Remember, taking proactive steps is crucial in managing your sexual health and preventing the spread of infections.
