Please! Any thoughts on my B-HCG

He
Please any thoughts on my beta's, I'm a little confuse w/the levels as most websites put it above high range and other at a lower end but I've seen many posts here and they seem higher than mine so I think I shouldn't worry about a molar (like I thought)
Test BFP: at 14dpo VVStrongline
1st b-hcg at 4w2d: 188
2nd b-hcg at 4w5d: 911
Are my levels ok? Not sure if that is normal if it's too low, to high, or too fast? 
Any thoughts.. 
Thanks..
