Constant worrying

Am I the only mum to be who is constantly worried about losing her baby? People keep telling me awful miscarriage stories and it's frightening the life out of me. I'm only 9 weeks atm and have got to wait at least another 2 weeks for my first scan and to hear the heartbeat. I worrying as I know it's no good for me and the baby but I just want to know everything's ok. Epically seen as most of my symptoms have gone apart from being extremely emotional and tired. My breasts are a little tender but nothing like they were before. 😔
