Can bacterial vaginosis come and go? (untreated)

So I got BV 2 times earlier this year and It had been a few months since then and Now I think I have it again. I got it like a month ago or so but I have no insuranve so I cant go to the doctor yet. The foul odor was there but rn, its not there or it doesnt seem to be. Can the odor come and go with BV or is there a possibility the BV went away on its own?
