Hcg levels go from 16000 to 13000 in 1 week?

HCG levels typically double every 2-3 days during early pregnancy. A decrease in HCG levels by 20% or more over a period of 2-3 days may be a sign of a potential miscarriage. However, it is important to note that HCG levels can fluctuate and may not always follow a strict pattern. If you are concerned about your HCG levels, it is best to discuss them with your healthcare provider.
