Hcg levels are not a good indicator. At 5w3d with my first daughter my levels were 11000 and at 5w6 days they were 32000 and I only had one. Next pregnancy at 4w1d my level was 49 and a week later like 800 and again I only had one.
When i found out i was pregnant i was almost 2months and my HCG levels were 370 so yea numbers can not tell you how many your having, and everyones HCG levels are different
That isn't necessarily high but it is important to remember that hcg should double approx every 48 hours and hcg is NOT a good indicator of how many babies are in there.
Congrats
