Pregnant with a BV

So I am currently 11w3dys pregnant I got a call from my OB saying that I have a bacterial vaginosis and they prescribed me some medication but they told me to not drink it till the end of my first trimester and tbh I’m freaking out cause I’m worried that it’ll cause me problems and or worse a miscarriage and idk I’m a mess right now I have to wait 5 more days to drink my medication and I have this for about 3 weeks almost four idk what to do
