HCG results at 4+2

Paris

Got my results back for my first HCG blood test that I took at 4 weeks, 2 days. They read as 813 mIU/ml which I’ve read is pretty high for 4 weeks. Anyone know if that could possibly indicate something wrong, or twins?! I got another test taken yesterday morning to see if it doubles, I should know the results later today or tomorrow but I’ll be 5 weeks tomorrow.
