It was right for my 2 boys my neice andall my co workers out of 10 9 was right i really believe that after asking people so go around and ask people how old was they when they concieved and the month....but for the person who asked her mom maybe she got the mounth she concieved wrong or the age she conceived maybe they was early or she gave you the age she was when she had them but then again who knows maybe its just pure coincidence
