I should be Happy ...

I recently found out I was pregnant again a little after September 11th ,I had a miscarriage in July hardest thing i think I ever had to go through.As I took the pregnancy and saw the positive line believe me I was exited but my husband said I was emotionless he asked aren't you happy he was so excited but me I didn't know what to feel is this Normal ,I feel like its not the same joy after you experience a miscarriage because of that constant worry its like I can't enjoy my pregnancy without worrying or being paranoid I will be 7 weeks tomorrow and I'm over asking what if it happens again is the baby okay does it have a strong heart beat I want to tell my family so bad but I can't will this be the same outcome as last time heres me telling them I'm pregnant again then I'm telling them that the baby no longer had a heartbeat ...I'm praying to God every day that my babys okay , I hate this feeling I feel like I'm a bad person to feel this way 😕 😞. Is this Normal? Has anyone had a successful pregnancy after a miscarriage
