Severe nausea and fatigue

Last period started on Jan 16th.. I have been having nausea and dizziness since Sunday.. I took a test this evening and it was negative. Also noticed increased fatigue, sensitive to smells, and heavy CM in the last week.. I’m planning on taking another test Sunday AM. No changes in breast and no spotting. I’m usually abnormal as far as periods go so I didn’t think anything of it as far as being late.. I’ve ever had nausea like this tho. Any insight you may have would be appreciated.. ❤️
