Ladies I need your help, I wanted to find out what were having but my partner wants the surprise, looking at the calendar it says I'm having a girl as my Chinese lunar age is 36 even though I'm 35 ( I think you add a year but there are calculators on the web to work this out for you just search for the calendar and it's usually attached)
What I would like to know is all those ladies who know what there having to test it out is it correct for you, please let me know. 
You look up your lunar age at the side then month of conception st the top and the box tells you boy or girl .
