Neg. test night before AF start date.

Karly
I took a test at 9 tonight and it came out negative. For the last week I've been nauseous, I've had heartburn, bad gas, bloating, headaches, cramps, and sore nipples. My boobs are always sore before AF but never my nipples. I'm going to test in the morning but am afraid of another negative. Does anyone have any insight or advice?
