Kinda bummed out 😔

Hi girls I'm currently 7dpo I think and this is our 3rd TTC cycle I got a positive opk on jun 3rd and 4th so I'm cycle day 16 or 17 I'm hoping this one sticks bbuutt I've been watching all kinds of YouTube videos of women getting a BFP at 6 dpo and 7 dpo and then i came across a homemade of test using bleach and if it fizzles it's a ➕and if it foams over or does nothing it's a ➖ so out of curiosity I tried it and welp it was a ➖😔😭 so it kinda bummed me out idk why I let it get to me and I know I still have some time to really find out but I was just wondering have any of you guys tried this and did it work? Was it true ? I'd really like to know
