I am pregnant since 12 weeks. On Saturday evening, I started losing a bit of brown blood. My doctor told me when this happens, come to me right away, but well saturday evening. After checking many blogs, I decide to just call the Charite to know if I should go or not. I was told to come right away, so I did. They made me wait 2 hours to tell me that next time I should not come because it is not an emergency. When I told them that I was told to come, they explained that their personnel is not qualified to know what is an emergency and what is not. Well How should I know if not even them are able to tell me?
