3 days before missed period and still testing negative, could I still be pregnant?

I have a ton of pregnancy symptoms, nausea at random points throughout the day (but no vomiting), tired, bloated lower abdominal cramps and my intuition just tells me that I am pregnant. I just FEEL it, you know!?! But all that to say I’ve taken a few tests and they all say negative... this would be our second baby and I am praying that we are pregnant. We only “tried” once but that’s all it took with our first (fingers crossed it’s the same with baby #2). Could I still be pregnant? The wait to test later in the week is killing me... the tests that claim they can test up to 5 days sooner but I’m still showing negative is killing me. The same happened with my first baby, I tested and tested and didn’t show positive until 3 days after my missed period. Has anyone else not shown positive until after a few days following missed period- or am I just weird? Praying for baby #2!!!!
