Symptom please help!

Heather • Nursing student, raising two beautiful boys and have a loving hubby! I`m the queen of my own castle!
Took a test this morning it was negative. But for past week I have felt. Funny feeling in my stomach, tender boobs, nasuase, smells bother me, emotional. Could this mean I'm pregnant but not enough Hgc to detect. Plus i usually have cramps a few days before my period and nothing. Period is suppose to be here tomorrow. How long should
​I wait to test again????
