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.
The first three Peach Bowls were played at Grant Field on the Georgia Tech campus in Atlanta. Between 1971 and 1991, Atlanta-Fulton County Stadium hosted the game. Since 1992, the Georgia Dome has played host.
NFL owners voted to award Super Bowl XXXVIII to Houston during their November 1, 2000 meeting held in Atlanta. This was the first Super Bowl to be played in a stadium with a retractable roof (but it was eventually closed during the game). It also marked the first time in 4 tries that the Patriots played a Super Bowl that was not in New Orleans.
