Thanks for the query.
Generally the beta HCG
levels should be above 25,000 at 10 weeks. So as per this your levels are normal. Your doctor might have called to see the doubling time of the levels.
But usually the beta HCG levels will decrease after 10 weeks, so no need to bother about it.
As your previous scan was normal and your spotting stopped. you may not have problems in future.
