As a pregnancy grows, HCG increases. Measurements of HCG levels can be useful during the early weeks before the fetal heartbeat is seen on ultrasound, usually around 6-7 weeks after last menstrual period, or 4-5 weeks after conception.rom 1200-6000, the HCG usually takes 72-96 hours to double. Above 6000 IU, the hCG often takes over four days to double. So, the rate of increase in HCG levels normally varies as a pregnancy progresses.
