Advice!!?

I will be 5 weeks pregnant tomorrow! This is our second child. Our first son is 2 :)I have the worst anxiety that what if I have a miscarriage. How do yall ease your mind? I have normal small cramps, no symptoms of one. It is just a constant fear from hearing so many stories:( I cannot wait to figure out my first doctor appointment and see the baby. I think my mind will be set to ease a lot then:(
