Hey all!! 03/28 af is due!

Aunt flow is to make her debut 03/28 unless there is an itty bitty baby growing. I took a pregnancy test 7dpo which was neg, I kinda expected that, but I just feel different.... 
Symptoms have been, light annoying cramping(not a normal PMS symptom), nausea before and after meals, smells(lemons and others body odor have been the most intense), tiredness, and vivid dreams. Some bloatedness but that's not uncommon for me before aunt flow. Anyone else experiencing some symptoms? Or just feeling different?
