Dr called for a second blood test. Should I be worried??

Afternoon ladies, I went to the Dr on the 14th and got confirmation on pregnancy, I’m a little scared because they called me in to do another blood to make sure my hcg levels are rising. My first blood results came back I was 4.5 weeks pregnant. Is this normal for them to call you back in to check levels? This is my second child, third pregnancy. This would be my rainbow baby after waiting for years.
