As Soon as Symptoms Appear
No waiting period. If you have discharge with a fishy smell, book.
The commonest cause of changed discharge, and it is not a sexually transmitted infection. Treating it as thrush is the commonest mistake, and it is why so many people go through repeated antifungals that were never going to work. A swab settles it.
Bacterial vaginosis is the commonest cause of unusual vaginal discharge in women of reproductive age. The characteristic sign is a thin grey or white discharge with a distinct fishy smell, often more noticeable after sex or during your period. Itching is less typical than with thrush, which is one of the ways they differ.
BV is not a sexually transmitted infection. The vagina normally contains a population of lactobacilli that keep it slightly acidic. In BV, those are outnumbered by other bacteria, and the acidity falls. Sex can disturb that balance, which is why BV is more common in sexually active women, but you are not catching it from anybody and your partner has not given it to you.
Treatment is a short course of antibiotics, either tablets or a vaginal gel, and it works quickly. The frustration with BV is not treating it, it is that it comes back for a lot of women. That part is worth a proper conversation rather than another identical prescription.
No waiting period. If you have discharge with a fishy smell, book.
Mention it when you book. BV in pregnancy is associated with preterm birth, so it is treated rather than left, and some treatments are preferred over others.
Recurrent BV, meaning three or more episodes in a year, deserves a longer appointment and a different approach rather than another standard course.
Usually available across all ten clinics, Monday to Friday 8am to 7pm and Saturday mornings.
Step 1
Same-day slots available. Female clinician on request.

Step 4
Antibiotic tablets or vaginal gel, plus practical advice on reducing recurrence.

A healthy vagina contains a large population of lactobacilli, bacteria that produce lactic acid and keep the environment acidic, at a pH of roughly 3.8 to 4.5. That acidity suppresses other organisms. In bacterial vaginosis the lactobacilli are displaced by a mixed population of other bacteria, including Gardnerella vaginalis, and the pH rises. The fishy smell comes from amines those bacteria produce, which become more volatile in alkaline conditions, which is exactly why the smell is worse after semen exposure.
On why it recurs. Treatment reliably clears the overgrowth, but it does not restore the protective lactobacilli, and it is their absence that allows the whole thing to happen again. That is why over half of women treated for BV have another episode within a year. Recurrence is a property of the condition, not a sign that treatment failed or that you did something wrong.
Why it is worth treating rather than ignoring, even though it is not dangerous in itself: BV raises the risk of acquiring STIs including HIV, because the loss of acidity removes a defence. It is associated with pelvic inflammatory disease following gynaecological procedures. And in pregnancy it is associated with preterm birth and late miscarriage, which is why it is treated in pregnancy rather than left.
On approaches to recurrence. Options include longer or repeated courses, suppressive treatment with vaginal gel used intermittently over months, and removing the triggers, especially washes and douching. Evidence for probiotics and for lactic acid gels is mixed but some women find them helpful. Testing and treating a male partner does not prevent recurrence and is not recommended; for women with female partners, concurrent treatment is sometimes considered. Your clinician will go through what applies to you.

| Treatment | Prescribed, £25 plus medication | Free prescription or standard charge |
Said plainly: NHS care for BV is entirely adequate and free, and pharmacies also sell treatments for confirmed BV. Private care is worth paying for when you want it confirmed by testing rather than assumed, when you want a next day result, or when recurrence needs an unhurried appointment to work through properly.
No. It is an imbalance in your own vaginal bacteria. Sex can disturb that balance, but it is not transmitted from a partner.
BV typically gives thin grey discharge with a fishy smell and little itching. Thrush typically gives thick white discharge with marked itching and soreness. They overlap enough that a swab is the reliable way to tell.
Because treatment clears the overgrowth without restoring the protective lactobacilli. Over half of women have another episode within a year. It is a feature of the condition, not a failure on your part.
Pharmacy treatments exist for confirmed BV. If you have not had it confirmed, or previous treatment has not worked, getting it tested is more useful than guessing again.
Not directly, though it is associated with pelvic inflammatory disease after gynaecological procedures, and PID can affect fertility.
The evidence is mixed. Some women find them useful and they are unlikely to do harm. We will be honest that this is not settled.
Distinctly fishy, and often stronger after sex or during your period.
A short course of metronidazole, as tablets or a vaginal gel. It works quickly.
For a male partner, no, and treating him does not reduce your recurrence. For a female partner, concurrent treatment is sometimes considered, and worth discussing.
No, it makes it worse, and it is one of the commonest causes. Plain water externally is all that is needed.
Yes, BV in pregnancy is associated with preterm birth and late miscarriage, so it is treated. Tell us if you are pregnant.
It is usually fine, though avoid alcohol with metronidazole, and note that condoms are advisable since semen worsens symptoms.
Book a confidential appointment at your nearest clinic. Tested rather than guessed, treated the same day where appropriate, and a real plan if it keeps returning.
