Key Takeaways
  • Abnormal discharge, pelvic pain, and bleeding between periods are among the most common signs of an STI in women.
  • Many women have no symptoms at all — untreated chlamydia or gonorrhoea can still lead to pelvic inflammatory disease (PID).
  • A standard HIV test does not screen for other STIs like chlamydia or gonorrhoea.
  • CA Medlynks packages range from KES 5,000 to KES 30,000, with most results ready in 24 to 72 hours.
Seek medical care urgently if you have severe lower-abdominal pain with fever, or if you are pregnant and notice any of these symptoms — these need prompt evaluation. Also seek care urgently if a possible HIV exposure was within the last 72 hours; PEP may be an option but only within this window. Call CA Medlynks on +254 741 669 175.

Common STI Symptoms in Women

These are the signs to watch for — but their absence doesn't rule out an infection.

  • Abnormal vaginal discharge (unusual colour, smell, or amount)
  • Pain or burning during urination
  • Pelvic pain or pain during sex
  • Bleeding between periods or after sex
  • Sores, blisters, or bumps around the vagina or vulva
  • Many women have no symptoms, and untreated chlamydia or gonorrhoea can lead to pelvic inflammatory disease (PID) and fertility complications.

STI Prevalence in Women: What the Data Shows

Curable STIs are more common among women in the region than many people expect.

Chlamydia prevalence increased by over 35% in sub-Saharan Africa between 2010 and 2020.
Common curable STIs like Trichomoniasis (6.8%) and Chlamydia (6.6%) are significantly more prevalent than HIV (4.5%) among women in the region.
Young women aged 15 to 24 years face a disproportionately higher burden of curable STIs compared to men.

Why Some Women Have No Symptoms at All

Feeling fine doesn't mean nothing is there.

  • Chlamydia, gonorrhoea, and even HIV may cause no symptoms at all, especially during the early stages.
  • Even if you feel healthy, you may still pass the infection to your partner.

The Risk of Leaving It Untreated: PID and Pregnancy

Most bacterial STIs are highly treatable — early diagnosis is what makes that true.

  • Untreated chlamydia or gonorrhoea can lead to pelvic inflammatory disease (PID) and fertility complications.
  • If you're pregnant or planning pregnancy, untreated STIs can also affect the pregnancy — another reason early testing matters.
  • Most bacterial STIs are highly treatable when diagnosed early.

If You Test Positive: Getting Treated

Testing positive can feel overwhelming, but most STIs are treatable.

If your results show an infection, CA Medlynks provides discreet medical guidance through consultation with our medical doctors.

Do You Need an HIV Test, or a Full STI Panel?

These are not the same test.

  • A standard HIV test does not detect chlamydia, gonorrhoea, herpes, HPV, or trichomoniasis.
  • If you have symptoms, a comprehensive STI panel is usually recommended instead of an HIV test alone.

Not sure how soon to test after a possible exposure? Timing depends on the test method — see our guide on how soon after sex you should get tested.

Frequently Asked Questions

Common questions about STI symptoms in women and testing.

Q What are the most common STI symptoms in women? +
Abnormal vaginal discharge, pain or burning during urination, pelvic pain or pain during sex, bleeding between periods or after sex, and sores or bumps around the vagina or vulva are the most common. Many women have no symptoms at all, so a negative symptom check doesn't rule out infection.
Q Can I have an STI with no symptoms at all? +
Yes. Chlamydia, gonorrhoea, and HIV can all cause no symptoms, especially early on. Even if you feel healthy, you may still pass the infection to a partner. Regular testing is the only reliable way to know your status.
Q Can untreated STIs affect pregnancy or fertility? +
Yes. Untreated chlamydia or gonorrhoea can lead to pelvic inflammatory disease (PID) and fertility complications. If you're pregnant or planning pregnancy, untreated STIs can also affect the pregnancy, which is another reason early testing matters.
Q Is a standard HIV test enough to check for STIs? +
No. A standard HIV test does not detect chlamydia, gonorrhoea, herpes, HPV, or trichomoniasis. If you have symptoms, a comprehensive STI panel is usually recommended instead of an HIV test alone.
Q How much does STI testing cost at CA Medlynks and how long do results take? +
CA Medlynks packages range from KES 5,000 to KES 30,000 depending on how many infections are covered. Most results are ready within 24 to 72 hours, and rapid HIV tests are available the same day.
