Has anyone had Bacterial Vaginosis or taken Metronidazole in pregnancy? I'm 17+6 and discovered lots of dark blood in my pants earlier today, and I'm still bleeding now. Rang midwife who told me to go to A&E, which I did and the obstetric doctor found heartbeat with doppler (thank god!) but didn't do a scan. She suspected a vaginal or bladder infection and took a swab and urine sample and I'll call for results in 2 days. She was convinced it's Bacterial Vaginosis, which I've had before years ago but never with bleeding, and gave me Metronidazole antibiotics to take. Is it likely to be BV?? Anyone had bleeding at 18ish weeks or had BV before? Feeling v stressed!!
