Blood tests

My hcg has not doubled, it did go from 300s to 500s though. And my progesterone went up as expected. More blood work tomorrow. I am 5w 3d. Nurse said she was very optimistic since I was still going up but I am a complete mess now. 😭 Anyone have words of reassurance here? Trusting that God has a plan but MAN am I all tied up about this now.
