The interface is very intuitive, and the Ob-Gyn's or any other Provider of Prenatal care would certainly welcome it. Just enter name, select "Cycle Frequency", select date last menstrual period started and click "Calculate". If unsure about last menstrual period, just use dates from sonogram if one was done. PregnaCalc (©) is FREE FOR USE by anyone, it is fully functional, nothing is disabled, and it has no time limitations.
