How do you not worry after a miscarriage

I am pregnant with my rainbow baby(4 weeks 3days) and every little pain I feel I get worried.

The pregnancy I had the miscarriage with I was constantly cramping and my test were always faint, at 5 weeks I had the miscarriage.

This pregnancy I don't have any cramping just today some pulling burning pain every once in awhile when i move a certain way. I know its normal but how do you not worry 😭😭 .

I am waiting on my insurance so I can get into the doctor to check my levels.

I found out I was pregnant by blood test at the hospital (levels 53.6 at 3 weeks 6 days) and I took a test yesterday with a dark line.

I didnt go to the ER for that, I went to another reason.
