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
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
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.
