what are signs of pregnancy???

Okay so me and my (now ex😕) had sex last Two weeks ago. My period was due two days ago and still hasn't came. I woke up today feeling nauseous and looked online about how to take a home pregnancy test. You have to put some urine in sugar and if it dissolves then your not but mine didn't dissolve it kind of sat on top. When I first poured it in it made a hole but I assume that was from pouring it. Can someone please help me??
