Take another pregnancy test?

Ashley • Mommy to a sweet little man!
My period isn't due for another 5 days but I went ahead and took a pregnancy test. It was a test that can read positive up to 6 days before your missed period. It was negative this morning and I'm wondering if I should go ahead and wait or just go ahead and assume I'm not pregnant. I've had nausea, my breasts are heavy and are leaking, I've been cranky, exhausted, and having milky white watery discharge (sorry if tmi!). Could I have psyched my body out enough to experience all of these symptoms? I'm not on birth control and I never have these symptoms from PMS. I've also had these symptoms from two days after i conceived (I was ovulating that day but we did use a condom).
