Hi! Has anyone tried the dyi baking soda pregnancy test to determine if they had conceived? If so what did you not that indicated a postive or negative? Was it accurate? I just took one (getting antsy and don't have any store bought ones on hand). It's not my first morning urine and I'm about 7 dpo. I used 2 tbsp of baking soda and 2 tbsp of urine. When I combined them it got all foamy pretty much instantly (see picture). I did some research online but am still super unclear. Thoughts?
