Your input would be appreciated

Ladies, my AF is 5 days late within the 1st 2 days I took 2 pregnancy test and both were negative, but my boobs are popping out of my bra, my lower back hurts, and I'm peeing ALL the time. Maybe it's in my head. I guess I'm just wondering what the earliest symptoms were for you gals when you got pregnant. And when I should take another test? I'm beginning to give up and just let nature do its thing. I don't want to take another test and have it be a BFN. I'm sad. And could use your responses.
