Scared to get pregnant

5 years ago I suffered a ruptured ectopic pregnancy and had 1 of my tubes removed. 3 years ago I conceived and had a beautiful little girl who is 2 in a months time. we then started trying again 4 months and I suffered a miscarriage at 9 weeks. we have now decided to start trying again but I'm so scared of it happening again. has anyone else been through something similar? I'm just so scared and feel so alone at the moment as I'm constantly worrying about every little thing.
