hello, <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>!

I need everyone's opinion, and experiences, please. I had unprotected sex, with a guy I was seeing a month ago, and now my period is late.. I have been experiencing things I've never really experienced before, like, nausea, dizziness, cramping, vomiting, fatigue really badly, and I can smell alot of weird smells, however I took a pregnancy test and it said not pregnant, does that rule the pregnancy out, or should I continue to test? any advice helps, thanks!
