Homemade pregnancy test?

I have a bad habit of going on YouTube and looking at live pregnancy tests. I seen this one that came up and it said live homemade pregnancy test. So I watched it. It's where you take urine and also bleach and use half and half. You pee in a cup and then put bleach in it after and you Should do it outside because if you are pregnant it will produce an awful smell and foam up completely. Has anyone ever tried this? I do not recommend. I was just wondering if anyone has tried it?
