Calculating the Period of Amenorrhea

  • All you have to do is count the number of days there were from the first day of the last menstrual cycle to the present day.(e.g.: March 20)
  • Take the first date of the last menstrual period. (e.g.: January 10th)
  • Deduct it from the number of dates in that month. (31-10=21)
  • Add the remaining days to it. (21+ 28(Feb)+20(March)=69 days)
  • Divide the number of days from 7. (69/7=9 weeks and 6 days) 
  • Then you have the POA in weeks
If you have any query, just leave it on comments, I am always looking forward to answer them all.

    I have appreciated the method and it really works, because is did the calculation with a specified LNMP and after used a pregnancy wheel and only got a difference of one day. thanks a lot for the method @Dr. Morris.
