Not Pregnant

This is my first time posting to this group so thanks for the support in advance. My husband and I have only been trying for a couple of months now but I’m already getting defeated seeing a negative test result time and time again. I’m 3 days late, nauseous, and breasts are very sore/swollen. I just took a test and got this. Does anyone else experience nausea prior to their cycles? Or thoughts that it is too early?
