Sexually transmitted infections often show no early symptoms in women, which is why they are frequently missed or discovered late. Many women in London experience mild signs such as light pelvic discomfort, spotting, or a burning sensation when urinating and assume these are due to stress or hormonal changes. Clinically, we see that these subtle early symptoms are some of the most important to recognise.
This guide explains the first signs of STDs in women, the infections that remain silent for months, what early symptoms can feel like, and how to identify possible infections even when symptoms are mild or unclear. You will also learn when to test, which symptoms require urgent attention and how Marylebone Diagnostic Centre offers fast, discreet and reliable sexual health testing.
What Are the First Signs of an STD in a Woman?
Early signs can be subtle, vague, or mistaken for normal changes. The first symptoms often include:
Most women experience mild or no symptoms, making testing essential.
What Is the Most Common Undetected STD?
The most commonly undetected STDs in women are:
Because symptoms are subtle or absent, infections develop quietly until they cause pelvic pain or fertility problems.
What Does the Beginning of an STD Feel Like?
Many women describe early symptoms as:
- A mild “twinge” or cramp in the lower abdomen
- A slight burning sensation after urinating
- A feeling of heat or irritation
- A subtle change in discharge
- Light pelvic pressure
- Burning after sex
- A sensation of dryness or tenderness
The beginning of an STD in a woman rarely causes dramatic symptoms.
Instead, it often feels like “something is not right.”

STD Stomach Pain in Females – What It Means
STD-related stomach or pelvic pain may feel like:
- A dull ache
- Pressure
- Mild cramps
- Pain during deep intercourse
- Lower abdominal heaviness
Chlamydia, gonorrhoea, mycoplasma, and untreated infections can cause stomach-like pain that becomes more noticeable with movement or after sex.
How to Know If You Have an STD Without Getting Tested (Female)
You cannot confirm an STD without testing.
However, symptoms that raise suspicion include:
- Burning when urinating
- Pain during sex
- Light spotting
- Unusual discharge
- Persistent pelvic ache
- Burning after sex
- Itching that does not settle
Testing is the only accurate way to know.
STD Symptoms in Females: Discharge Changes
Discharge may change in:
- Colour
- Volume
- Smell
- Thickness
However, early infections may have no noticeable discharge, which is why many infections go undiagnosed.
STD Symptoms in Males (For Comparison)
Men may show symptoms earlier, including:
- Burning when urinating
- Urethral itching
- Penile discharge
- Testicular discomfort
- Pain when ejaculating
This comparison helps couples understand why one partner may have symptoms and the other may not.
Early STD Symptoms in Males
Men may notice symptoms as early as:
- 2–7 days for gonorrhoea
- 7–21 days for chlamydia
- A few days to weeks for trichomonas
- 2–20 days for herpes if sores develop
Even without symptoms, men can carry and transmit infections.

Clinical Notes from MDC
Clinically, we see that early STD symptoms in women are often missed because they resemble normal hormonal or urinary changes. However, silent infections can lead to long-term issues such as pelvic inflammatory disease, scarring and fertility problems. Testing early and at the correct interval is essential.
Most infections are fully treatable when diagnosed quickly.
