advice on pregnancy after miscarriage

Last year I sadly went through a miscarriage I believe I was around 7-8 weeks when it happened.     Just 2 days ago I found out I'm pregnant I'm supposibly 4weeks now.   I'm terrified I'm going to lose this baby to.  I do feel better with this pregnancy (even though I'm still early)  I don't feel like it's going to happen this time.   But if you have ever had a miscarriage it's still hard not to think about it.    For those who have gone through this can I get some advice on how to calm myself down, or even hear your stories on how you got through it on the pregnancies after.
