No, I don’t believe that your abortion would cause such a thing.

A lot of women suffer from chronic BV. (bacterial vaginosis). A leading culprit in it seems to be an exposure to semen in the vagina. Semen is alkaline and your vagina is acidic – the introduction of semen into the vagina causes the PH balance to be thrown off – causing for an over growth of bad bacteria (gardnerella). Also, near the time of your period your hormone levels drop and this can cause for bacteria overgrowth.
Other factors can be related to stress, tight fitting clothing, washing the vaginal area with perfumed soaps, etc….

A lot of women also have little, sometimes, no success with antibiotic treatment. There are other methods of keeping the PH balance normal such as taking Acidophulus supplements. 2billion+ per dosage. Also yogurt is found to help, plain yogurt only. There’s a product called Rephresh which restores the vaginal PH – but it is costly and not a permanent long term solution.

good luck.

Abortions can sometimes increase the chances of a woman developing Bacterial Vaginosis.
