Need help

I have been feeling nauseous all week. Eating foods I don't getting hot when im anemic and stay cold. Also been going pee alot. I didn't have a period last month due to stress and haven't had one this month. Took a test on the 12th and looks negative to me. Should I wait another week and retest? I have like all the pregnancy symptoms but then again this is how I felt a few months ago and nothing.
