Question: How Long Does It Take for hCG To Drop to Zero After a Miscarriage?
Answer:
The exact length of time for hCG to leave your system after a miscarriage depends on how high the hCG level was at the time that the pregnancy stopped developing.
The average span of time is that the hCG can disappear from your system in anywhere from 9 to 35 days. In general, a woman who had a very early miscarriage is likely to have her hCG return to zero faster than someone whose loss occurred later.
