Baking soda gender test?

Jacqie • I am a stay at home mother five. I`ve been married for almost 8 years. We are due in March with baby #6!
I am 18 weeks today and have just recently heard of the baking soda test to find out the gender of the baby. How acurate has it been for those of you that have taken it and is it to late in my pregnancy to take it?
