Homemade pregnancy test

I think I might be pregnant but I don't have any money to buy a pregnancy test right now so I figured I would try these homemade test (I will be buying an actual pregnancy test soon though because I know these test aren't very accurate) I 'm just confused by the results because I did the bleach test right when I woke up yesterday and it reacted almost immediately, it was like frothy or kinda looked like beer haha but then I did it in the afternoon again and nothing really happened so I did another test which was the baking soda and I did it in the evening but when I did it there was no reaction at all then this morning right when I woke up I went to the bathroom and redid the baking soda test and it actually reacted unlike the day before. Why do you think it does that and what do you think are my actual results?
