Hcg levels

At 3 weeks 3 days my HCG was 67... 2 days later 3 weeks 5 days it was 226. Yesterday, 3 days later at 4 weeks it was 712... is that a good number for 4 weeks? I feel like it’s pretty high and jumped from 226...?

Suffered miscarriage and ectopic previous and my HCG never got this high so I’m happy but just wanna know it’s normal. Thoughts?
