Hcg

Dear dr. Shed,
I have 2 questions about my pregnancy. I have concerns about my Hcg levels which are rising higher than normal in 48h. At 4+2 weeks HCG is 2856. Is it normal? Are there any exact HCG result or signs of molar/extopic pregnancy?
The other question is for that we have concert ticket for openair stadium venue, but i have had 2 miscarriages before. Could be any risk for the baby if we attend it?
Thank you for your help.
