What Safe Treatment Can I Use For Suspected Bacterial Vaginosis Or Vaginitis During Early Pregnancy?

Hi, I believe to have either bacterial vaginosis or vaginitis. My symptoms include itching and discomfort during sex. I am also 4-5 weeks pregnant, I have tried contacting my health provider, unfortunately, haven't gotten a callback and I called two times. What medicine would be safe to treat the infection while pregnant?
