hello bao bao, ya, your lunar age should be 27, provided that you are not borned in Jan (before CNY), cos if before 1978 CNY, you have to add another one year, that means you have to add 2 years. Please tell me if that is the case.
Anyway, i have tried for you, the predictor said is a girl.
Ok, let me demonstrate, my conception month is April and my LMP was 7 April 2005 and i should have conceived from 16-30 April (roughly) and this period is lunar month March. So, i keyed in my lunar age and month of conception March (instead of April). Is that clear?
