Am I freaking out for nothing?

Destynie • July 19th 🎀 KerriAnn🎀 💜
I miscarried in May, my hcg at four weeks was 25. I'm now pregnant again and at four weeks my level is 63, my midwife sent me in for another test I have to go to tomorrow, but am I over reacting? I'm not bleeding or cramping or anything like that besides sore breasts and EXTEME fatigue but I'm not feeling anything bad. Any ideas?
