Fifteen days of foul-smelling discharge, ten days of light bleeding — could this be infertility?

First of all, get well soon — what you've described requires some personalized precautions. Below are possible causes, brief self-care tips, and when you should seek immediate medical attention.

Possible causes (general, not a definitive diagnosis)

• Vaginal infections: bacterial vaginosis (sour/fishy odor), Candida fungus (itching, cheesy discharge), or trichomonas infection (abundant, foamy, foul-smelling discharge). Some infections can occur even without sexual intercourse. - Menstrual irregularities / hormonal fluctuations: stress, dietary changes, or hormonal reasons can cause irregular bleeding. - Minor intrauterine injury, cervical polyp, or other gynecological causes (especially bleeding, breakthrough bleeding).
• Rarely, other systemic causes besides infection (thyroid, etc.) or, although rare, sexually transmitted diseases — however, the probability is lower since you mentioned there was no sexual intercourse.

Brief self-care tips - Avoid vaginal douches and scented soaps; gently wash the outer area with lukewarm water. - Choose cotton underwear and avoid tight synthetic fabrics. - Change hygiene products frequently (be careful with pads and tampons).

• If bleeding increases or there is severe pain, do not use tampons; medical evaluation may be necessary. - pH tests or vaginal test kits sold in pharmacies can provide temporary information but do not replace a doctor's evaluation.

In which situations is urgent/priority evaluation necessary? - Very heavy bleeding (if it quickly wets pads every hour), fainting, severe abdominal/groin pain, high fever.

• Worsening bad odor, heavy yellow-green purulent discharge, severe itching, or burning during urination.
• If there has been sexual contact or there is a possibility of pregnancy: take a pregnancy test and consult a healthcare professional.

Recommended medical steps (consult a doctor immediately)

• Vaginal discharge sample taken during examination at a gynecology or health center (microscopy, culture, pH measurement, PCR/STI tests if necessary).
• Blood tests (complete blood count, hormones) may be ordered to assess bleeding if necessary. - The doctor will prescribe appropriate medication (antibiotic or antifungal); do not self-medicate.

In your case, the combination of foul-smelling, prolonged discharge and bleeding strengthens the possibility of infection; given your age (17), it would be appropriate to consult with an adolescent gynecologist or family doctor. If there are no urgent symptoms, schedule an appointment within a few days; seek immediate assistance if your condition worsens.

Even at a young age, your menstrual cycle may still be irregular; a normal menstrual cycle generally ranges from 21–35 days, but frequent changes are common during adolescence. Based on the information you provided, here are a few brief possibilities and suggestions:

Possibilities (not a definitive diagnosis)

• An infection or vaginal inflammation can cause breakthrough bleeding or spotting and abnormally foul-smelling discharge, which can affect the timing of your period. - Hormonal fluctuations (stress, sleep, dietary changes, puberty hormones) can lead to a delayed period. - Very rarely, a cervical polyp or other local causes can cause breakthrough bleeding.

What to expect/what to do - If your period is normally irregular, you may get your period within the next 1–2 weeks; however, this timeframe may be affected if there is an infection. - If foul-smelling, heavy discharge and spotting persist, it would be advisable to have an examination and vaginal culture/pH/microscopy at a healthcare facility as soon as possible — especially if the odor is pronounced and the discharge is excessive. - You mentioned that you have not had sexual intercourse; However, the probability of pregnancy is considered low, but a pregnancy test can be done if there is even the slightest doubt.

Situations requiring immediate evaluation (seek immediate help):

• Very heavy bleeding (wetting a pad/tampon quickly), fainting, severe abdominal/pelvic pain, high fever. - Worsening discharge, thick yellow-green pus, severe burning, or pain while urinating.

In the short term: pay attention to hygiene rules, avoid scented products, prefer cotton underwear, and if improvement/menstruation does not start or worsens within a week, make an appointment with a gynecologist/family doctor or obstetrician. I am not a real doctor and this is not a medical diagnosis.

Based on your previous information and considering your age (17), here are a few brief, personalized points:

• Prolonged wetness (e.g., constantly using damp pads/tampons, wearing wet swimsuits/jumpsuits for extended periods, frequent long baths) can disrupt the natural flora of the vaginal area. This can:

• Predispose to bacterial vaginosis or yeast infections (increased discharge, odor, sometimes slight bleeding/irritation).

• Cause skin maceration (softening, irritation) and itching or discharge due to fungal/skin irritation. - Chlorinated water, such as pool/jacuzzi water, or dirty open water can increase the risk of infection and contribute to bad odor.

• What you can do immediately:

• Change wet swimsuits or underwear immediately; choose loose, cotton clothing.

• Gently dry the area (gently with tampon paper or a clean towel), avoid excessive washing and soap/shower products. - Avoid scented pads/devices/showers; lukewarm water is sufficient for daily hygiene. - Seek immediate medical attention if you experience pain, fever, or burning during urination, or if your discharge is yellow/green, frothy, or has a very foul odor.

• Priority for medical evaluation:

• If you have foul-smelling discharge and intermenstrual bleeding that has lasted for 15 days, it is advisable to see a gynecologist or family physician/adolescent health care provider within two to seven business days. - If the discharge worsens, bleeding increases, you develop a high fever, or experience severe pelvic pain/dizziness, go to the emergency room.

• Diagnosis and treatment: Examination and vaginal swab/culture/pH/microscopic examination may be necessary; appropriate treatment (antibiotics/antifungal, etc.) will be planned by the physician. Specifically mention this 15-day history of continuous wetness and the foul-smelling discharge + intermenstrual bleeding during your consultation; this affects the priority of evaluation and treatment.

Based on the information you have (17 years old, heavy, foul-smelling discharge for 15 days; light bleeding for 10 days; prolonged wetness; no active sexual life), here are the approximate probability ranges (not definitive, only guiding):

• Recommendation for immediate/priority doctor visit (within 1-3 days): 60-80% Reason: foul-smelling, long-standing discharge and intermittent bleeding; infection (bacterial vaginosis, yeast infection, other vaginal infections) is highly likely and may require treatment.

• Early but non-urgent evaluation (appointment within a week is appropriate): 15-30% Reason: examination and swab/analysis are still recommended even if symptoms are mild or there is only slight discomfort.

• Immediate emergency room visit (immediately, within hours): 5-10% Reason: very heavy bleeding, severe pain, fainting, high fever, or severe systemic symptoms require urgent evaluation. If these symptoms are not present now, an emergency may not be necessary, but close monitoring is important.

Recommendation: Due to your symptoms (foul odor, discharge lasting 15 days, breakthrough bleeding), it is best to see a gynecologist, family doctor, or adolescent health clinic within 1-3 days. At the appointment, a discharge sample will be taken and tests will be performed if necessary; early assessment, rather than waiting at home, allows for faster recovery if an infection is present.

Seek immediate medical attention if you experience urgent symptoms: very heavy bleeding, fainting, severe pelvic pain, high fever, severe burning during urination, or rapidly worsening discharge.

Short answer: No, what you've described doesn't directly mean infertility. However, prolonged, foul-smelling discharge and intermittent bleeding can be a sign of infection; if proper evaluation and treatment are delayed, complications that can rarely affect fertility (e.g., intrapelvic infection and damage to the fallopian tubes) may develop. Therefore, acting quickly is important.

Why it shouldn't be immediately considered infertility: Infertility is usually associated with long-term, recurrent, or untreated serious pelvic infections; a single episode of vaginal discharge is often due to a reversible infection or a superficial problem (bacterial vaginosis, yeast infection, etc.). As you mentioned, if there is no sexual intercourse, the risk of sexually transmitted infections is low; however, non-sexual causes such as bacterial vaginosis or yeast infections are common and usually resolve with appropriate treatment.

What to do now (prioritize):

• Get evaluated at a healthcare facility as soon as possible (within 1-3 days): gynecological examination and vaginal swab/pH/microscopy or culture. This is necessary for accurate diagnosis and appropriate treatment. - If the doctor finds an infection, most problems resolve completely with early treatment, thus minimizing the risk to fertility. - If you experience severe upper/lower abdominal pain, fever, heavy bleeding, or fainting during the examination, go to the emergency room.

Notes on long-term fertility: - Vaginal/cervical infections that are treated early and appropriately usually do not impair reproductive function. - Recurrent or untreated pelvic infections are evaluated later; if there are concerns about fertility, talk to a gynecologist and, if necessary, undergo visual examinations (ultrasound, HSG, etc.).

Practical advice now: - Change wet clothes/wet pads immediately, gently dry the area, and avoid scented products. - Do not self-medicate; your doctor will provide appropriate treatment. - More specific information (risk assessment for fertility, etc.) can be given after the examination, depending on your condition and test results.
