Can Bv Cause Bleeding During Pregnancy

Can Bv Cause Bleeding During Pregnancy – Is My Baby In Trouble?

There is no concrete evidence to suggest Bv causes bleeding during pregnancy, it can be a whole host of other things that could be a contributing factor. Some doctors believe that if bv is left untreated, overtime it will raise the risk of pelvic inflammatory disease which is a completely separate condition. But one of the symptoms of PID is vaginal bleeding.

It’s really hard to find a correlation between bv and bleeding during pregnancy. So the answer to the question: Can Bv Cause Bleeding During Pregnancy is…

It’s possible but we need to look at scientific journals and women who have had bv during pregnancy. Only then can we come to a rational conclusion

Does BV Affect Any Part Of The Pregnancy Period

Can Bv Cause Bleeding During Pregnancy

Studies carried out show that having bv when your pregnant is linked to an increase in preterm birth and a low birth weight baby. Other links include preterm premature rupture of the membranes and uterine infection.

What Is Preterm

Also known as premature birth, it is basically when a baby is born before 37 weeks. These babies are known as preemies or premies and are at greater risk of diseases such as: Cerebral palsy, slow development and sight problems. Symptoms of preterm birth can be seen if you have contractions which happen more often than every 10 minutes or leaking of the vagina.

What Is Preterm Premature Rupture Of The Membranes

This condition is basically the rupturing of the fetal membrane before the normal time of labour and happens from 37 weeks onward. Most women witness labour within 24 hours of rupturing their membranes but 6% of women will not be in spontaneous labour within 96 hours.

A thing to note is, the earlier the rupture happens, the less likely that the onset of labour will be within a specified time period. This condition is associated with 40% of preterm deliveries and leads to significant morbidity and mortality.

Another interesting point to note is, Vaginal Bleeding is one of the risk factors associated with this condition and can happen at any time during pregnancy. So this might be the issue you are noticing if you are bleeding but it can’t be 100% certain. Constant monitoring by a professional will need to take place to diagnose this.

What Is Uterine Infection

Uterine infections are often linked to an increase of bacteria that multiply and travel from the vagina to the uterus. An infection in the uterus can be dangerous because the infection might affect the placenta, harm the developing baby or lead to birth abnormalities.

It can also make labour are more dangerous procedure with some people experiencing organ failure. Treatment for this kind of infection are through antibiotics but may require hospitalisation.

Bv Linked To Miscarriage?

Can Bv Cause Bleeding During Pregnancy

There are a few studies which have seen a connection between bv causing an increased chance of miscarriage. A study carried out in 1999 examined bv cases. 771 women were selected and out of those 190 (24.6%) had bacterial vaginosis. 22 women (31.6%) with bacterial vaginosis who conceived had a much higher risk of miscarriage in the First Trimester compared with 27 women (18.5%) who had a normal vaginal flora.

The study also took into account other risks factors such as smoking, maternal age, no previous live birth and polycystic ovaries but the risk still stayed at a high level.

However, i don’t want to place too much emphasis on these studies because the link between BV and pregnancy complications isn’t perfectly clear.

Experts still don’t know why only some women with BV end up delivering prematurely. They also don’t know if BV directly causes complications such as PPROM or if women who are predisposed to other infections or problems that may lead to these complications are also more likely to have BV.

Many Women with BV have perfectly normal pregnancies. And up to half of the cases of BV in pregnant women resolve on their own.

Does Bv Cause Bleeding In General?

Yes bv often does cause bleeding but this is accompanied by other discharges, most common one being a thick whitish fluid. If BV travels through the vaginal canal to the cervix, it can cause spotting or light bleeding after intercourse.

Usually this isn’t something you should worry about unless the bleeding is very heavy and continuous.

A study was carried out in the 90s with 42 patients who had irregular bleeding episodes or discharge. All the participants had all the tell-tale signs of bv. Treatment gave a cure rate of 76% versus 5% in the placebo group.

The bacteria: Mobiluncus sp. was identified in 81% of these cases before treatment, in 8% of the cured patients and in 50% of those not initially cured at follow-up. Repeated treatments, once or twice, resulted in a 100% cure rate.

A 6-month follow-up was carried out on 39 of the 42 patients and showed only 7 relapses giving a cure rate of 82%. After the successful treatment all bleeding disappeared. This proved that bv does indeed cause bleeding.

Treatment Options If I Have Bv During Pregnancy

Generally speaking, bv is not screened for during pregnancy or prenatal care, so if you have any concerns or show symptoms of bv you need to inform your doctor so they can investigate further and maybe do some testing.

There are various treatment options available, most of them being Antibiotics.

Oral Medication

Clindamycin 300 mg or Metronidazole 500 mg are the common treatments given to patients because of their great ability to fight a whole host of bacterial infections. They need to be taken twice daily for 7 days straight.

Topical medications

These medicines are available as a cream that you insert into your vagina to kill off the infection. Clindamycin 5 g or Metronidazole is administered just before bedtime for 5 days. Hopefully your bv should have cleared up within this period.

An important point to mention is you need to avoid alcohol during this treatment for at least one day after completing the procedure. This is to stop any abdominal pain, nausea or stomach pain this medication can cause.


You must of heard about the major problems we are currently facing in regard to antibiotics. It’s fast becoming a health crisis. Bacteria can mutate and evolve at a very rapid rate which helps them become resistant to medication. There is no doubt in my mind that the bacteria involved in bv may also be undergoing a transformation.

Heck, did you know that around 50-60% of bv case patients relapse and the condition comes back. It’s very hard to get rid of. The only surefire way you can fix this problem once and for all is to restore the natural flora of the vagina. Reducing the acidic environment is the first crucial step.

Can Bv Cause Bleeding During Pregnancy


Bv by itself does not cause severe bleeding during pregnancy, it does play a part but there are other factors involved which might be the underlying cause of the problem. Pelvic inflammatory disease is the more likely culprit as that can also cause bleeding during pregnancy.

Although Bv has been linked to various complications during pregnancy, it does not contribute massively as previously thought but there has not been enough research carried out in this area for professionals to be 100% certain about the links it has to miscarriage.

Don’t worry too much that you cause undue stress on the baby and yourself, just be wary that if you see any sign of bv just get it checked by your doctor. I would also recommend you look into some natural treatment options to get to the root of the problem which is the imbalance in your vaginal flora.
