Any information

Any nurses, midwives, people on here that have experience or knowledge with BV? I got diagnosed with it April 30 and took the meds. All seemed fine. Then yesterday I went into for cramping and back pain and I have it again, or it never went away. I’m so scared for my son and feel like I can’t even enjoy this pregnancy. I’m on medication again. I’ve never had it before so I went to google and found out that it can cause harm to my baby. Is that just if left untreated? My doctor didn’t seem concerned and didn’t really even give me much information.

Thanks so much!
