There are established normal levels of fluid for each week of pregnancy, so your levels will be compared with these. In general, an AFI of 5cm (2in) or less, or a deepest pocket measurement of less than 2cm (0.8in), is considered to be low (Nabhan and Abdelmoula 2008, RCOG 2002) .he amount of amniotic fluid increases as your pregnancy progresses. You start off with just a few millilitres, but will have between 800ml (1.4 pints) and 1,000ml (1.6 pints) by the time you're about 36 weeks pregnant (Carter 2012) .
In general, at around three weeks of pregnancy your hCG levels will be between 5 and 50 mIU/ml. At around the 4th week, hCG levels will be between 5 and 426 mIU/ml. At week 5, the range jumps to 18 to 7,340 mIU/ml. By week 6, it is between 1,080 and 56,500 mIU/ml. During weeks 7 and 8 of the first trimester, hCG levels will rise to between 7, 650 to 229,000 mIU/ml. HCG levels during the first trimester will peak sometime around 9 to 12 weeks of pregnancy, at somewhere around 25,700 to 288,000 mIU/ml. By the final weeks of the first trimester week 13 and 14, hCG levels are finally on the decline, and will be at around 13,300 â 254,000 mIU/ml.
