Pregnant After Misscarriage

I lost my first pregnancy in May this year at around 9 weeks after the baby stopped developing around week 5-6.... Iv just found out I'm pregnant which based of my dates puts me on week 6 tommorow... I'm so anxious nervous and paranoid because I don't want to go through another misscarriage, I'm struggling to feel happy about my pregnancy because I was so happy last time and hot told at 9 week scan I was to miscarry any day... Anyone ever been in my shoes?
