A.S.
I have a friend that swears by the chinese birth chart and it works for her I guess. But, for me, I don't trust it. According to the chart for my age and my 1st child she was supposed to be a boy from 2 months before conception until 3 months after conception. The chart was way off for her. But almost every chart was off. So I can't say I would trust it 100%.
Good luck though. I wish you the best.
