Hello! Can you please tell me who might have had this? For the past 10 weeks and 5 days, at work recently I saw brown discharge, called an ambulance, they brought me to the hospital, they looked at me in a chair said there's no threat only erosion, that's it, it's bleeding slightly, told me not to drink anything, noticed brown discharge again at night, is it dangerous? The doctor said if there are symptoms of pregnancy, then the baby is alive, I feel nauseous! Tell me, has anyone else experienced this? Is erosion dangerous?
