So hard not knowing!

I am 6w1d and just found out my hcg was 500 when I got my blood drawn yesterday. I am going again tomorrow, but my midwife said this could be low or normal depending on when I ovulated. I can't take this waiting! I'm so nervous! I miscarried in February and just want a healthy baby. My levels were low last time and I can't even think about it happening again. Praying for good results! Words of encouragement please!
