Positive blood test new years eve, turned 40 new years day

Ni

So this is my 2nd time being pregnant- i had a miscarriage back in August. Im about 4 weeks now and cannot control the nervous, anxious thoughts about another MC. My hcg is good but im not really having any symptoms- a little cramping, which i know is normal, but its not everyday. Is this normal? Did anybody feel differently at this point?
