Discouraged

Amanda
This is my second pregnancy. My first one ended in miscarriage and I honestly thought that once I hit 12 weeks I'd be so excited and feel great. Well I'm 18 weeks and yes I'm very excited but can't shake this feeling like something is wrong. I know it sounds weird but my first pregnancy I just kept thinking this is going to end in miscarriage and it did and now I feel like I'm going to go to my anatomy scan Friday and there will be something wrong with my baby or my baby won't be alive. Every appointment I go to the baby has a great heart beat and my dr says I'm in perfect health but i just can't help but feel like something is wrong. I don't feel the baby move and I'm not showing yet and that doesn't help. Am I the only one who feels like this?
