Bacterial Vaginosis

All my life I have been dealing with bacterial vaginosis. Everyone I have been put on medication it just burns me even more down there and makes it extremely painful. I finally found that if I keep taking acidophilus once a day ir cleared up on its own and I have been free from it for 3 years now. I just recently found out that I am pregnant and I am so excited. I'm 6 weeks and the symptoms of bacterial vaginosis is coming back :( Things are out of balance. I'm afraid to go take any medication because it will just make it worse, but I'm scared because u heard it can cause miscarriages. I don't know what to do? My doctor is closed. Should I just continue taking acidophilus in hopes it clears itself?
