Scared...

Well I'm turning 8 weeks on Wednesday & I have only a few symptoms. I'm really tired all the time and just don't feel like doing anything & I'm REALLY emotional. I honestly don't feel pregnant because I literally have no symptoms. & im really scared because I had a miscarriage April 2015. But I know I'm not having a miscarriage because I have no bleeding at all. & no cramps... Does anyone else feel this way?
