Pregnant ? 💕

I'm not sure. My test came up negative but I've been having symptoms... Neausea, vomiting, heartburn, bloating, white discharge, cravings, and food aversions.  I would be no more then three weeks. How much longer should I wait to take the next test? I found out I was pregnant with my first at four weeks through a blood test. I had symptoms with him almost right after conception...
