No such thing: There is no such thing as an accurate homemade baking soda pregnancy test, nor a baking powder pregnancy test, nor a cream of tartar test. Home urine pregnancy tests are cheap to buy, sold everywhere, and accurate by 3 weeks after sex or 1 week after missing a regular period.

Pregnancy test: You can purchase a pregnancy test for as little as 99 cents & get accurate results. A homemade test made of baking soda would not be accurate.
