help!

Hi there, I'm having an issue with a vaginal discharge but I don't believe its yeast. it's not white/pastey like a typical yeast infection but more mucousy (sorry to be so descriptive). I had this problem twice before and have gone to my ob/gyn and i tested positive for a strep b infection, they gave me Antibiotics to treat it, which did take care of it but obviously only temporarily. can anyone recommend a natural cure to get this under control for good? thx
