Cervicitis: symptoms, treatment, and when to worry
Last updated September 3, 2026.
Cervicitis is inflammation of the cervix, the lower end of the womb, most often caused by a sexually transmitted infection. It can cause unusual discharge, bleeding between periods or after sex, and pain during sex, or no symptoms at all. It is diagnosed on examination and treated with antibiotics targeted at the cause.
What causes it?
Sexually transmitted infections are the usual cause: chlamydia and gonorrhea lead the list, with trichomoniasis, herpes, and Mycoplasma genitalium also implicated. Non-infectious causes include irritation from douches, spermicides, or a forgotten tampon, and allergic reactions to latex. Sometimes no cause is found. Because the symptom-free version is common, cervicitis is often found at a routine smear or STI screen rather than because something felt wrong.
What actually helps?
- Get tested rather than guessing: the examination and swabs identify the organism, and treatment targets it. Sexual health and GUM clinics do this routinely, without judgment.
- Antibiotics treat the infection: the regimen depends on the cause, and finishing the course matters. Partners may need testing and treatment too, or the infection ping-pongs.
- Abstain until treatment completes: sex during treatment risks reinfection and transmission; clinics give specific advice on when it is safe to resume.
- Remove irritants: stop douching and any product that preceded symptoms.
- Do not sit on it: untreated infective cervicitis can ascend into the womb and tubes, pelvic inflammatory disease, which threatens fertility. Treatment is quick; the complication is not.
When is it an emergency?
Cervicitis is not an emergency, but get same-day care for severe lower abdominal pain with fever, vomiting, or feeling very unwell, since that pattern suggests the infection has spread upward. Heavy vaginal bleeding or severe pain also warrant urgent assessment. Otherwise, symptoms like persistent discharge or bleeding after sex deserve a routine appointment promptly rather than eventually.

Common questions
Is cervicitis an STI?
Usually it is caused by one, chlamydia and gonorrhea most often, but cervicitis itself is the inflammation, not the infection, and it has non-STI causes too: irritants like douches, latex sensitivity, or a retained tampon. The swab results determine which story applies. Either way it is common, routine for clinics, and treatable.
Can cervicitis go away on its own?
Mild irritant cervicitis may settle once the irritant is removed, but infective cervicitis generally persists without antibiotics, and the risk of waiting is ascent into the womb and fallopian tubes, pelvic inflammatory disease, which can damage fertility. Given that a swab and a short antibiotic course usually settle it, watchful waiting is the bad bet.
How is cervicitis diagnosed?
On examination: the cervix may look inflamed and bleed easily when touched, and swabs are taken for chlamydia, gonorrhea, and other organisms, often with a pregnancy test and a check of the discharge under a microscope. It is frequently first noticed at a routine cervical screening appointment. The process is quick and standard at any sexual health clinic.
Does my partner need treatment if I have cervicitis?
When an STI is the cause, yes: partners need testing and usually treatment, otherwise reinfection ping-pongs between you. Clinics handle partner notification sensitively and anonymously if preferred. Sex pauses until both partners complete treatment. Non-infective cervicitis needs none of this, which is one more reason the swabs come before the assumptions.
Can cervicitis affect pregnancy or fertility?
Untreated infective cervicitis in pregnancy is linked to complications including early labor, so it is tested for and treated. Outside pregnancy, the fertility risk comes from untreated infection ascending to pelvic inflammatory disease, which scars the fallopian tubes. Treated promptly, cervicitis does not threaten fertility. This is the practical case for not ignoring discharge and irregular bleeding.
Why do I keep getting cervicitis back?
Recurrence usually has one of three explanations: reinfection from an untreated partner, an organism the first antibiotic did not cover, or a non-infectious cause still in place, douching and irritants being the common ones. Persistent or recurrent cervicitis after proper treatment warrants re-testing, including for Mycoplasma genitalium, and a specialist sexual health review.
