Gender prediction game for fun

Okay had to share ☺️
Take the month you last had a period+your age at conception. 
Ex: September (9)+(24) =33
Now do 49- (answer from previous equation). 
Ex: 49-33=16 
Now you are going to subtract 1 from that number and then 2 then 3 until you can't subtract any more. 
Ex: 16-1=15
15-2=13
13-3=10
10-4=6
6-5=1 
1-6=can't do 
so my answer is 1 
 
If your final answer is odd it means girl. If it's even it means boy. 
According to this I am having a girl ☺️
Hopefully it's true but I just throught it was something different and wanted to share☺️
