Metronidazole & BV

Lucy

So I'm almost 18 weeks pregnant. And my midwife said I have BV and would need to take Metronidazole 500mg for 7 days to treat it. Of course I looked it up & I read it's not safe to take during pregnancy o,0 & of course my annoying self is now worried. Anyone go through this? I'd love some input 😭
