I have stringy yellow discharge – is this the BV biofilm?

Does the dying off of the biofilm with BV create any discharge? I have a stringy yellowish discharge and faint cramps. 

It would be wonderful if the biofilm was so easy to spot but unfortunately, it isn’t quite as simple as that.

As far as we are aware, the biofilm is not an entity that is visible to the naked eye, though it can be seen under a microscope. The biofilm is not likely to be expunged from the vagina so dramatically.

The biofilm dissolves relatively slowly, which would probably add to discharge, but it isn’t something that will be purged in such an obvious way.

Bacteria are tiny and while the biofilm is made of a matrix that includes microbes, it isn’t very thick.

Yellowish discharge is most often associated with aerobic vaginitis. You can give it a couple of days and see if it continues – it may be a mixture of treatments and discharge and just need to be cleared from your vagina.

Faint cramps are not unheard of, but do indicate something happening further up than just the vagina.
